Re: Hard starting when cold
Hi I'll attempt to clear a few things up.
As far as 1,2,7,8 Number 8 They call a choke unloader, is refered to as a choke pull off. It is a diaphram, on the passenger side of the carb I believe, that cracks the choke open about 1/8 inch when it gets vacuum.
4 and 5 Yes the carb has to be partially dissassembled. Might as well remove it to avoid dropping small screws down the carb.
I had very similar issues when I first got my truck and had no knowledge of these quadrajets. I ended up putting a basic holley carb on the truck and had no dissapointments. One pump in the dead of winter and it fires right up.
I also rebuilt my quadrajet, reinstalled it, and it works excellent. I don't exactly know what was wrong I just replaced the gaskets, needle, seat, float..... everything in the kit.
My carb is the non-feedback model and the truck has no check engine light. You mentioned you have am E4ME- I think thats what mine is.
Hopefully something here will help you out. Good luck
-Jeremy
