hatchsub Posted October 19, 2005 Share Posted October 19, 2005 Well...now that its getting colder again my bad hessitation is back. If i let the car warm up all the way its fine and runs smooth and doesn't hessitate much if at all. But if i start it and try to run it when its only partially warm then it has the tendancy to bog down or stall on me off of idle. It has the dreaded Carter/Weber carb on it but my old 86 with a hitachi used to do this too and that had a bunch more miles on it. I don't know what to do short of replacing every damn vacuum line under the hood. I know the other option is the weber carb which i think i will do in the near future when i have the funds for it (and a hitachi intake as well). Any suggestions for me guys? Is there one particular vacuum hose under the hood that causes this more than others or is it just the carb itself and should i live with it until i get the funds for a weber?

Syonyk Posted October 19, 2005 Share Posted October 19, 2005 Interesting. My 87 GL (SPFI) does the exact same thing - a stumble off idle or around 2000 RPM when it's cold, runs perfectly when it's warm. -=Russ=- Link to comment Share on other sites More sharing options...
waimaks Posted October 19, 2005 Share Posted October 19, 2005 My stock 81 Brat does exactly the same thing, yet it has a manual choke. Link to comment Share on other sites More sharing options...
cmiller Posted October 19, 2005 Share Posted October 19, 2005 From my experience both of my carbed GL's that I had ran rough when cold, maybe just the nature of the carbed beast? My SPFI EA82 idles right up on a cold start because of the fuel injection, new coil didn't hurt either. Link to comment Share on other sites More sharing options...
wintersubaru Posted October 19, 2005 Share Posted October 19, 2005 Allmost every carbed sube i have ever drivin needed at least a 5 minute warm up.The 86 i have now has only three vacum lines,One for advance for disty one for heater control and one for choke and it still needs a five minute warm up or it will stumble like heck untill it warms up 1/4 of the way on gauge.

archemitis Posted October 19, 2005 Share Posted October 19, 2005 um... guys... thats what carburetors do. they dont have an enrichener, they have a choke. the choke just chokes the engine of air, so it runs richer. no making power when your choke is closed, or partialy closed. efi motors shouldnt do this as bad, because they just richen the mixture up. you can still get alot of air in the motor, and the extra fuel makes it run ok untill its warmed up you can adjust your choke, and maybe make it a little better, or just let it warm up for a couple minutes. its truly the nature of carbureted engines.

hatchsub Posted October 19, 2005 Author Share Posted October 19, 2005 Well im talking once i kick the choke off. If i kick it off after a couple of minutes it will still stumble. Only when its fully warmed up will it run nice. Link to comment Share on other sites More sharing options...
84gl Posted October 19, 2005 Share Posted October 19, 2005 take the choke apart the round black unit that work the choke has a heating coil in it check to see if it is broken if is try to solder a heater rezister in its place works great on my 80 sedan Link to comment Share on other sites More sharing options...
Durania Posted October 20, 2005 Share Posted October 20, 2005 What mine does is it will idle really high (2000 RPM) range and then it takes about 5 minutes really to get running good; you know everything is working when you hear a loud backfire and see wildlife fleeing the side of the highway Link to comment Share on other sites More sharing options...
