my carb wont hold idle. and on my other carb the bowl gets too full. really needs help.

gonna post a video soon.

been messin with the idle mixture screw but no luck.

the exhaust smoke is blue btw

this is the video

My suggestion would be to check your float level on your carb if the bowl is too full, and by your video I'm assuming you have a vacuum leak which could be causing your car not to idle,

 

cheers!

What PCV setup do you have on it?

on the second vid the bowl was actually full didnt know why but i fixed it on the first vid. now it just sits above the dot but it does not idle.

gonna go look for vacuum leaks thanks

 

i believe its the closed setup. PCV-->catch can-->manifold.

Try cleaning the jetts and all passages inside the carby perhaps.

did all that before putting the carb back in. before it was hesitating on acceleration now it doesnt.

it holds idle now but its unstable maybe idle fuel mixture?

i believe its the closed setup. PCV-->catch can-->manifold.

 

OK, so long as the PCV seals under vacuum, otherwise it will leak air into the manfold at idle. At idle the PCV should be closed and fumes go into the air cleaner via that second vent. When you accelerate the air flow reverses.

 

Is the idle mixture screw turned in & out until you get maximum rpm on a hot motor?? I usually leave it on the "inwards' side of max rpm. Ignition timing, idle speed screw, float level and choke all affect it.

Did you check the fuel cutoff solinoid ?

@altezza dude i put on the air cleaner assembly it idles a little fine now. maybe ill check the timing. i don't have a timing light right now I'm still kinda playin around with the idle mixture.

it idles between 1000-1500 it varies. below 1000 it dies.

i took it out today to get it registered but on the way home i think the alternator died because chg light on the dash does not come on and the battery got drained.

 

which one is the fuel cutoff solenoid @andy
