No more choke for me - pics
 

Well, I finally got tired of dealing with my retarded choke so now it is outa there. I personally think it helps the general appearance and now I can see the rear sight glass. Not that its a big deal or anything. I also took the extra crap off of there that is no longer needed. Check them out and tell me what you think...

what is all that black crap on the inside of your carb?

Can't you see ? He's an alien, for Chrissakes ! He can't tell you. Anyway you wouldn't understand.

wow inciteful post!

It is some dirt that came off of the choke butterfly rod. I guess thats what you could call it. You pull the rod out of the side and since it was dirty, some got scraped off and fell in. I knew after looking at the pics again that someone would ask what it was. Oh well.

Will it start in cold weather? I've never seriously considered removing the choke because I didn't think it would start in colder weather. I store my car during the winter, but there are plenty of times I drive it when it's cold enough to need (I think) a choke. Let me know how it goes, fellow Iowan ;-)

My choke has had some issues for awhile. I just turned the idle speed up to about 1K and it seems to be ok. I have to feather it quite a bit to keep it running, but other than that it pretty much doesnt have any issues. Mine is getting stored once I get my other 2 projects done. Should be in a couple weeks or so. Also my cold start assist, hot start assist, and basically anything that doesnt really need to be there as far as engine running goes has been removed.

Ian, plug the holes on the sides where the choke rod was. Otherwise youll be sucking unfiltered air into the carb. You can restore the fast idle linkage so your choke knob will still perform that function for easier cold starting.

Hey ian, I don't think mine would start (in the cold) without the choke either. I like the clean look though. Its also a way to save a pound or two.

Its all good. I kinda like knowing that I am the only one that can start my car and keep it going. Is it safe to remove the dashpot? All it does is helps close the throttle at the very end of the pedal right? I mean, it closes it softly as to not wear stuff out. I am not really worried about it wearing out per se. Also if I use JB weld to plug the holes is that going to hinder you in any way when you get that carb? I can use RTV if it will.

I thought the dashpot was to help keep the cat(s) alive. I removed mine.

nice. the stock carb looks so much better that way to me. i wish i could figure out how to take the choke off of the mikuni carb. anyone know?

We have the same carb setup, but my stock choke cable broke. I got a new cable with knob ( still says "choke" and the same size) that has a black outer cover. It looks and works great. It was a new part from the Snapper dealer ! I swear ! :)

looks good, i thought about removing all of the electronic stuff, and just using a manual cable for mine

Looks pretty clean there Ian :)

Mine's also missing the altitude compensator, the dashpot, and the vac secs... it's a Sterling/Carl carb ;)

I find that removing all that CRAP from the carb, combined with taking out the rat's nest makes tuning and tweaking alot easier :)

And Carl's right, mine has the fast idle linkage hooked to the choke, so I can still cold-start it.. not that I drive it in the Winter or anything... but I start it in the fall every day for a week before storage.

Sweet. I may hook the fast idle back up but that is what was being stupid. It would work sometimes and not others so I figure now I know it will never work hehe. I may mess with it sometime when I am bored. I am most likely going to remove the dashpot also since I can.

I think you will end up putting that choke back on during the winter if you drive your rx7 through the winter. Mine wont start when its cold, it wont cough, it wont do anything but act dead. I close the choke, starts up with a couple pumps of the gas. I just cant forsee my engine being that much different, when it comes to start up, Im in Cali as well ( I didnt catch where your from tho). Hmmm

My car starts ok with 2 pumps AFTER I start it the first time and let it die. If I dont do it that way, it will flood and then the real fun begins lol. It has not ever not started for me. It started last night and it was 30 out.

When you first get into your car in the morning, and turn it over, if it coughs, yes the two pumps normally works fine, im interested in knowing in a month if you still have it like this. hehehe

I will, because it will be stored before then. My daily driver is an 01 protege so i dont have to worry about chokes.

i dont use my choke. i just grab my screwdriver and crank up the idle!!

I live in SW Missouri and all I have on mine is the fast idle. Pump it twice, feather the throttle a little then set the fast idle at about 1500 rpm and it will worm up great. I rebuilt my carb when I took all the "stuff off of it" that will cause it to run out a lot smoother. After it's warmed up. I can shut it off for a while and fires up on the first engine rotation. Carl is right, You need to plug the openings there the rod ran threw the carb. I used plugs a little larger so they fit good and tight. I made a custom breather so you can see the carb. I have some shots of the engine on my website.

I told my grandfather about this, and he was wondering: would having no choke reduce engine life?

His point was that you'd have so much gas flooding the combustion chamber, and washing the oil from the walls, that you would be much more likely to damage the seals and housings.
This is from his experience with piston engines, so he was wondering if it would be any different on a rotary.

Think about it. How would you have all this raw gas going in there? The throttle plates are virtually closed, acting as a sort of choke in and of itself. So at this point its running fuel off the idle circuts and not the main as theres not enough airflow flow to pull fuel thru the main system, or the transitional circuts either.


Ian, plug the holes with whatever, saves me the work later. :D I use the proper size ball bearings to plug those. And we dont use the dashpot on our carbs either.

I removed the dashpot contact thingie on the linkage rod assembly today. :D
