Won't idle anymore.....and seems to flood?

<< < (2/5) > >>

77cruiser:
I had a super rich idle at one time after some idle tuning mods, kept going leaner & leaner on the idle circuit, still rich.  Only thing I could find was one of the sec. idle bleeds was plugged.
I don't know if it was siphoning or what.

Cliff Ruggles:
They don't use good parts in those builds so for sure it should work better with one of my kits installed.  Keep us updated....tks...

fussfeld:
Main body to base plate screws:

Any particular/general torque settings?   Or just get 'em snug?

Cliff Ruggles:
Pretty much as tight as you can get them with a flat blade screwdriver and use lock washers on the screws as those thick gaskets will compress some with time.......

tayto:
Maybe others will say other wise,but after heat cycling the carb a dozen or more times over the course of a week or 2 i will come back when the engine is stone cold and go over all the screws again. I think aside from over tightening the 4 mounting bolts a lot of people will tighten the screws down with engine hot and cause warping.
