I was drunk yesturday(sad i know)

My rebuild kit finaly came in. SO I took most of the carb apart. It looks like I got most of the vacum secondary and chock off. I am not certain. I have a bonch of **** all over the floor. My drunk **** problably knocked everything off the table and then allover the floor.

anyway.. I started it. guess i better finish it.

I keep getting stripped screws. Anyone know the best way to take those old screws out with out damageing them? (yeah, i used pb. carb sat soaked for a day in it)

Anyone know of a way to get damaged screws out without damageing anything else..ie without a drill?



Are there any performance gains be removeing the shutter valve?


I am going to leave the carb sitting in pb for a 3 days.. see if that helps. I think someone with a really big arm tighten those screws.

I know I have more questions. The most important might be locating someone(that can be trusted) "maybe" finish the rebuild that I am (f word+ ing) up.

 

There is now way to get those screws out with out a drill. And it is advised that you remove the shutter valve. That will give a smoother flow and less restirction.

 

Vice grips.

Might wanna leave carb mod suggestions to Sterling or RX7Carl.

Use a flat head screwdriver, and use a hammer lightly to seat it really well. Then just break the suckers loose. And yea, my first rebuild was REALLY drunk. All went well got it entirely apart in 1 night....like 2 damn weeks trying to remember how to get it togeather...lots of spare parts now.

 

...so, removing the shutter valve is a plus? I mean it actually smooths out the performance? If that's the case, I am going to dig mine out of there, should have done it when I rebuilt my carb last month. Which incidentally, the kit sucked A$$, no new jets, floats, needle valves, just alot of gaskets and crap. (was my first rebuild on my own) went well, car screams, but it's ported as well, hmmmm the shutter valve huh? (it idles a bit rough right now)

 

Perfect example of why you should leave it to the experts. And also why you should check post counts on occasion.

 

well.. Its still soaking. I hope pb works. Maybe In should have bought a gallon of pb and just droped the carb in it. I am also makeing a block plate for the ACV valve. Its going to be made out of aluminum. wow when I took it off there was lots of 'crap' in there. Must be from the exhaust.

The kit I bought has a bunch of gaskets and stuff. I plan on cleaning everything thats metal very good and doing some polishing.

Anyone have a link or pic of a carb thats been striped of everything that it doesn't need?

 

I don't think post counts will tell you anything besides how many posts some one has posted.

 

yea man, people hang out in the lounge and post about **** and pitbulls and **** and have like 3000 post. they dont know **** about rx7s. to get those screws out with out stripping them in the first place use a good 14.4 cordless drill with a phillips or flat head and just push on the screw with all your weight and squeeze the trigger real slow. drills have mad torque, more than you can turn. plus you use your weight to keep evrything together, you dont have to worry about turning anything.

 

Lounge posts dont add to your post count. They used to though.

Anyway back to the topic. There are a number of ways to get them out. Im assuming your talking about the screws that hold the top of the carb on. Vice grips on the flank of the screw head will get some of them to break loose. What I use since I do carbs on the side is this.

Very handy tool. Cheap, effective and requires no power of any kind. Look in your local tool place for one.

Actually now I use a regular air powered impact gun, but that was my tool of choice for a while.

And if you need new screws, email me. Ill sell em cheap and I have all the required lenghts.

BTW- I like to drink too, but drinking and carb work dont mix. Youll screw something up for sure. Its like flying, driving, performing surgery drunk. Its never a pretty sight.

 

Cool tool Carl! I'll have to pick one of those babies up...

Anyway, vice grips worked for me as advised by Carl....

 

Carl, thanks for the heads up on the tool. For nine bucks you can't beat that.

 

i take a lot of offense to that comment. I know my stuff, I've been on this board for a long time but i don't post a lot. i read this board every morning at 8 or 9 ish. and then again at 4ish while i'm at work. I know a lot of things but ussually if someone else answers something i'm not gona answere it too. Your comment it crap for a few reasons.
A) define an expert. Someone who knows there stuff and posts on here all the time and has 50,000 posts?, someone who has 50,000 post and doesn't know anything? or someone who does know but has a low post count? You can't define an expert based on post counts. Just because you don't think someone who repled to a topic is an expert doesn't mean that they don't know what they are talking about. If the apexwarrior wanted just rx7carl or sterlings opinion then he would have PM'ed them. He asked the board though and in so doing so asked for everyones thoughts.
B) You're automatically assuming that burners85gsl-se doesn't know what he's talking about. And your at the same time saying that he's wrong. He had a valid option for fixing the problem. Their are special drill bits for geting stripped bolts and screw out. It your carful you can do it just fine. IMO i wouldn't choose that route but that's my opinion and that doesn't mean that he's wrong. I kept my mouth shut because while i don't agree with it someone else might see that idea as better suited for them.
C ) While Sterling and rx7carl are very knowledgable there are also other very knowledgable people on this board such as rx7doctor and robert (680wrph.....).
D ) I'm sure i speak for a few people on this board when i say this, I feel like i am a very knowledgable person and before i even offered an idea you told me to shut up.

I don't know you but maybe you are knowledgable about rx7's or maybe you arn't but i feel that those type of comments have no place in a community such as this.

 

For me, I used the simplest solution. Most of my stripped screws were in places where I could clamp vice grips down on them. they're round, but they have big enough edges that if your vice grips aren't dull you can grab 'em. Works like a charm.

Edit: about the shutter valve thingy. LEAVE THE BUTTERFLY THERE. JBWeld the shaft so that the butterfly stays in the upright "wide open throttle" kinda position, and remove the actuator that makes it move. JBWeld or otherwise block the vacuum holes that make the actuator move. This is the best way to do it.

There is no performance to be gained by removing the shutter valve as it is. The hole was cut in the intake manifold with the idea that the shutter valve would be there. By taking it out, you actually induce *more* turbulance, and you aren't helping airflow.

Now I may only be an "airflow apprentice" compared to some folks, but I'll let personal experience speak here: the folks I know who've removed their shutter valve only achieved one thing - an 1100rpm idle that they couldn't bring down and no performance improvements. Not exactly a big deal, but not exactly an improvement.

I think even Carl has mentioned that you should leave the butterfly there at some point (correct me if I'm wrong Carl).

As for who is an "Expert" and who isn't - Post count doesn't tell the whole story, but it does tell *something*. If someone has been around this forum for a long time, chances are people can tell how good that person is in a given area. Rx7Carl and Sterling are our resident carb experts. I know that not because they have lots of posts, but because they have lots of *good* posts that I've read. It's harder for me to take the word of someone who has 27 posts over someone who'se got 800 and who I've seen give some good advice. Yes, real world experience counts for more than time on the forum, but I can't validate your experience by reading your 27 posts where you say "listen to me, I'm better than you, I know everything".

Grow up folks. Make an educated assessment of people by looking at *how* they write, *what* they write, and how they back themselves up. If they throw insults around when confronted with a different opinion, or start sparring back and forth in open forum, chances are they're not "experts". As for the post count, it takes only a few minutes to read a dozen of that person's previous posts by searching under their username.

13b4port, he didn't tell you to shut up. And burners didn't have a suggestion for the screw, he just said to take the shutter valve out. You might want to take some time to review your post with a cool head before posting.

 

Thanks for clearing that up, Viper.

 

Say Whaaaaaa?!
I dunwanna be no "expert. You get called an "expert" and you don't know the answer to a question, well then yo gotta make something up! Then it doesn't work and you get accused of giving bum advice...The whole damn thing snowballs into a giant mess! Before you know it yer saying terrible things about each others' Mamas and, well, it just gets ugly.

 

this is what i saw...

then the next post is

That kind grips me. because he didn't say anything about weather he was talking about the shutter valve, or the drill idea. he just basically said burners85gsl-se doesn't know what he's talking about.

then later on here it's obvious he was talking about the drilling idea because of this post.

Yea in his first post vise grips are a good idea but so is drilling. Saying "you might wanna leave carb mods sugestions to the people who know what they are talking about" is basically telling burners85gsl-se he doesn't know what he's talking about. And in so he is also infering that besides him (obviously) there are no other people that can help apexwarrior other than RX7carl, and sterling. which is in so telling everyone who is not rx7carl or steerling to not post because he's saying that before we get a chance we're wrong.

I thought about this for about an hour or so. That's a little explained better. It's not jsut hammmy though. I've noticed this behavior a lot more on this board. We're a community. All sugestions should be able to be said. Weather it's good or bad because the only way your gona know if it's a bad idea is if you or someone has tried it. But not only that, but someone who searches and has the same problem can search and find out that "o maybe i shouldn't use a drill because of such and what not can happen". But hammmy telling him to 'stop talking' pretty much, doesn't say anyting about why drilling would be bad or anything about the shutter valve. it just says 'you don't know what your talking about'.

 

You are completely wrong.

I did not tell burners he didn't know what he was talking about. That would be overly frank to the point of rudeness. Therefore, I suggested that he leave the shutter valve suggestion to the experts: in my opinion, and apparently Viper's, Sterling and RX7Carl. Not yours however, even though you've "been on this board for a long time". I didn't claim any special knowledge regarding the shutter valve, which is why I merely made the suggestion I knew would work--vice grips--and advised as to who I considered experts on the subject.

Sure enough, a few posts later we have someone picking up burner's suggestion as gospel. I again pointed out that you might want to look where the advice is coming from (44 posts), as that can be helpful "on occasion".

Technical communities are useless without valid information. Your search example, if this thread had gone according to your perfect world, would instead show that the shutter valve should be removed.

 

i'm done. i give up. i'm not gona try to keep explaining it. what you said was rude. very rude. your not the only one who's done this, i'm using you as an example. it's a tred i'm seeing more often here. but i'm not gona try anymore. screw it forget i even brought it up. what ever happened to politness and manors. i guess it's a think of the past on the net. o well.

 

I have come full circle and have allmost finished the carb rebuild. wow its looks alot differant then when I started. I had to use the drill only once, you know the floats? that they have some pointy things with springs attacted to them.. well the other part. the barrel with the holes. I used a big flat head and couldn't get it to move. I used a small enogh screwdriver( to wedge through the hole and turn it) and it snaped. Then I grabed then drill and a 1/4" driill bbit. whizzzzz whizzzz.. no problems

I got a chance to do machnical secondarys. easy as pie.

I got some photos for ya to look at.. let me know if I can leave these out.. I am going to JB weld some of the open holes.

the second pic : what hole can I block? can I remove the switch I am holding?

the third pic: Can I block off the round cilinder looking thing? Can I remove and block the thing with the black and red wires?

I am going to place the carb back on the motor tomorrow. AT which time I am also going to remove the actuator for the shutter valve and JB weld it open.
