But stock gasket will technically work

Rx7carl

Sure it will. It'll also block a bunch of airflow.

yea i got the gasket on today and trimmed it up. big difference. now i'm having a different problem all together. the trailign plugs are getting wet, but the leading plugs are bone dry. they are all brand new as of today. any ideas???

mwatson184

Are the trailing plugs even firing? See if you are getting spark from your trailing coil. Good luck.

lol, dude you rock. i swear that should have been obvious to me. i have just been stressing so hard on this car that its killing me. i'm a technician at dodge and i work on cars all day long, just to come home and not even be able to get my very own to run. it takes a toll on an automotive tech. i will check for spark and then see whats up.

FB II

checked for spark. everything is in great working order. might try mar3's gumout trick.

red_blast

goodness, zach, i'm sorry. that car has given you so much trouble. i hope you get roxy running like a champ soon.
thumbs up to you for still working with her.

beautimus! she almost cranked tonight. guess she was just flooded as hell from me trying to crank it before i actually adjusted the floats? i dunno but there was waayyyy tooo much gas in there. it started once then died within2 seconds. so i pulled the spark plugs out and stuffed paper towel in the holes and i'm letting it evaporate over night. i'll try again tomorrow. the gumout didnt do ****.

FB II

well, let it sit over night and all day with the spark plugs out. FIRED RIGHT UP FIRST TRY!!!!! i let it warm up and noticed it was running lean. wouldnt idle; so i turned it off and went to set the idle. i also went and bumped up the floats to make it not so lean. i guess i bumped them too much cause i flooded it again. AAHAHAHAH, damnit! so i'm doing the same procedure tonight. will not **** up tomorrow. hahahahahahaha (....< is a little drunk)

mwatson184

heh, looks like you will get it figured out eventually. You don't need to let it sit overnight though, just crank it over with the plugs out to blow all the fuel out of there. Clean off the plugs and should fire right up. You really need to get the float levels set right before you can do any tuning. Good luck tomorrow.

yea i know. thanks. i think i did have the floats set correctly. i think it was the idle mixture and my accel. pump settings. hahahha, anywho, the floats are now back to spec. i believe tomorrow should be a good day for my car and I. i would do it tonight, but i have been drinking and my woman needs some attention too i guess. LOL i cant wait though cause i plan to get it back on the dyno when this is drivable. WOOOOOO!

You can set the floats and everything with the car running so you know what you are doing and the effects of what you are doing. I believe you are on your way. I just tuned mine today after sitting for awhile, man was it rich, whoo.. But now all is good and running real strong.

FB II

everytime i try to adjust my floats with the car running gas squirts out under the nut! too much fuel pressure????

red13brx7

NO that is normal, fuel should be squirting out if you don't put pressure on the screw to keep the gasket closed, if you work with it you can figure it out. You can stiil turn the float adjuster with the screw just loose and then tighten it. What I do is, adjust it by hand, atleast sometimes, and keep the screw driver on the screw with some pressure and then when you are done adjusting, tighten the screw back up. Its not too hard to do, just takes some practice.

If I was you I wouldnt try to richen by messing with the floats. Set the floats to where you had them originally, with gas dribbling out of the hole. Then get the idle mix screws at 2 1/4 turns out. Try starting it, if it doesnt fire up with one peddle pump before you turn the key. Then turn the screw that will open your throttle plates, uh I dont know a half of turn or 1 turnclock wise. Turn the key again it should start and idle high. Adjust the throttle plate screw to idle down to about 1000-1250. Should be fine there, depending on what jets are installed and if the carb is in good working order. And make sure you get that fuel pressure regulator set to 6 psi.

Is this street ported?

FB II

813kr$; no it isnt streetported. and the idle mix screws i think are my problem. i have them only 1 turn out on both sides. guess i should turn them another 1 and 1/4 or so eh? i have set my floats back to spec but still havent had a chance to go out and crank it again cause it keeps raining when i get home. and i dont want the motor and the battery charger to get soaked. hahaha, hopefully tomorrow will be a nicer day.

mwatson184

Actually the starting point is 1.5 turns out. That is only a starting point though. Then just turn them until your idle is strongest/smoothest. There is no arbitrary amount of turns out that the idle will be best.

I'm planning on dropping in a street ported motor and a RB holley SP setup. Right now all i have is a RB street port exhaust. How much of a gain will I be expecting with this setup?

Also, what's the max tire/wheel combo for a 1st gen. I really don't wanna go bigger than a 16 because this car will see much track time, and weight is a bad thing.

813KR$

with my experience, which I have been playing with the idle mix alot lately and at the track, me engine likes atleast 2 turns out(Iam at 2.5 turns out). The leaner I go, the smoother the idle, but slower 1/8 mile times, the richer my idle the rougher the idle and quicker 1/8 times.

lovintha7: with a well tuned carb and low restriction exhaust, you should be around 200hp. I would go with light wieght 15" rims. You can get good 50 series tires, like 205's. Also if this is a 1st gen, look into Direct Fire Ignition and to save money you can use the 2nd gen coil.

mwatson184

What is your idle speed? You really shouldn't ever have to back more than 2 turns out. After you set your idle how far open are the throttle plates? If they are open enough to uncover the idle transfer slots then I would try drilling some holes in your throttle plates and then retuning the idle.

mwatson184:

No, Iam not doing any drilling! I idle at about 1250rpm's. I am not sure where you get your info from about only turning out 2 turns, but I have heard before to start at 2 1/4 turns out and go from there. I have track backed evidence my engine likes over 2 turns out! I tuned on the street and had leaned out my idle to 1/2 turn out, then went to the track and slowly richened my idle mix and knocked off almost 1/2 of a second off my 1/8 mile time and was bringing it down every run until my clutch master cylinder went out! What is your best time on the track and what setup are you running? My best time is 9.5 sec in the 1/8 mile.

mwatson184

Your idle is too high, unless you have a ported engine. Idle speed shouldn't have that much effect on you eight mile performance, perhaps you were just becoming more skilled while driving. All holley tuning books I have read, and my personal experience, say the same general thing. You shouldn't have to back your idle screws out more than two turns, if you do then you have problems elsewhere. One example:

http://www.fordmuscle.com/archives/1...y/index2.shtml

Just look around on the internet, there are hundreds of sites that say the same thing.

After i drilled a 1/8" hole in each throttle plate on my ported TII, it idled smoother and stronger than it ever did. I was also able to lower the idle speed from 1100 to 750. Sorry no times on my 80 yet, and I don't think i can compare the TII times to yours, apples and oranges there.

You can drop that idle down, if you can't there is something wrong, like a vacuum leak or something to that effect. My best time was 9.7, but i am going back this week expecting 9.5 or better. my car wasn't tuned at the time. and it had a big antifreeze leak from the water neck housing.

My 12a is street ported and I can get it to idle basically where ever I want it. I was not getting better at running the track I have ran many times before! Actually the longer I run the slower my times get if I dont tune the carb, because my shitty stock clutch gets warm and starts to slip! I have been all over the net and have a Holley tuning book.I dont see how their can be a prob if my times keep on dropping as I richen my idle mix. I had gone to the track thinking the other way around, leaner idle, richer jet, but had played with the idle mix and ran and my time dropped then I kept on richening and dropping my time until the clutch master cylinder prob.
