Re: Q-Jet frustration
Well, after a futile search on CL for a GM HEI, I broke down and got a replacement ignition module....$108 bucks, but she starts....I think that I have most of the carb issues found, but when she is hot, you have to floor it and then hold it down for a few seconds to get her to start....I know that this cannot be good for the engine (lacking oil pressure in the first moment of start up).....what am I missing now?

Re: Q-Jet frustration
Try putting on a phenolic spacer. It sounds to me like you are getting some vapor lock from the engine heat. The spacer will insulate the carb from the intake and stop the vapor lock.

The phenolic spacer would cause the choke rod to be too short and we would be back to no choke again... |

He did a stage two for my 402 and I'll never go back to EFI! I sent him all of my specs along with my slightly used E'brock 1904 and he sent me back a pot of gold! It ran right out of the box. All I did was set the APT (using the aid of my WBO2 monitor) and all is well.! |

Re: Q-Jet frustration
I had hot starting issues a few months ago because my choke wasn't opening all the way. As soon as I shut off the truck and it cooled down just a few degrees, the choke would be fully closed again. I finally went to home depot, bought a metal rod the same thickness as the manifold mounted choke rod was, and made a longer choke arm.
I actually made several... some for winter when auto choke requirements are different, and some for summer. It only takes about 3 minutes to change one out for a different size. |
