HEI distributer
I have a 1980 GMC 6 automatic and I am wondering if my original distributer is a HEI ignition. I would like to improve the way this GMC runs, as it sputters when cold and doesn't give very good gas mileage. It seems, that if I can upgrade the ignition maybe it would run better. Marvxyz1
Thanks for any possible input!!!!!!!!!! |

Re: HEI distributer
HEI started on these truck in 1975, and 80 should definitely have one. Putting points in one is like putting a hand crank on the crankshaft.

Re: HEI distributer
Sounds like you need to rebuild the carb....

Re: HEI distributer

Re: HEI distributer
Sounds like I should probably check the carb when the weather breaks.

Re: HEI distributer
Check the choke. I bet it is opening too fast for a cold carb. I adjust my carb twice a year. Summer and winter. I adjust the choke so it stays closed longer during the winter.
If it runs fine after it's warm/hot, the choke is a likely problem. Last edited by gchemist; 01-24-2008 at 10:03 AM. |
