I've replaced my cc carb and distributor with a non cc quad and an accell 51000 series electronic distributor that I had. Now the car runs beautifully. Perfectly smooth and strong, good idle, starts excellent cold, but... If you drive it for awhile and then stop someplace for 15 or 20 minutes it wont start. Crank and crank, foot to the floor or pump it no difference. About the third or fourth try, when the batterys starting to draw down it will start. When it finally starts there is no rough idle, no smell of gas it will just sit there and run smooth. If you stop the car and just try to restart it right away it fires right up.

Fuel pump, line routing etc is all the same as with the cc unit. Started fine with the cc unit. I was originally running the stock coil with the accel dist. but I've now switched to my jacobs ultra coil. No change. I tried to replace the ignition module. I've had the accel unit go bad before and they're redesigned now. But the new one I got from summit didnt work at all. So its getting shipped back.

Any other ideas? I'm going to have to try to figure this thing out this weekend.

 

What carb are you using?

 

"I've replaced my cc carb and distributor with a non cc quad "


A 78 elcamino quadrajet. Just rebuilt. I'm leaning more and more toward the phony accel distributor. Going to check the air gap for the pickup tomorrow. Allready had shaft wobble in this thing once. Accel products just dont impress me much, i've had too many problems.

I am open to other ideas though. Sometimes you need someone to come up with a new idea to get you started in the right direction. The ole brain locks up once in awhile.

 

Gotcha. "Quad" means "four" (as in "...dual quad, 4-speed, positraction 409..." - don't worry, I won't quit my day job), so unless you're more specific, like "quadrajet" or "q-jet", one can assume most anything.

Anyway, you're probably on the right track. "90% of carb problems are fixed with an ignition tune-up", to paraphrase an old one.

As for Accel products, I've often used their standard tune-up products, couldn't be more impressed with the coil & module I'm using. But, I've never used one of their complete distributors, which seems to be the source of most of the ill-will towards them.

 

Well the gap was wrong for sure. Re-set it, then tried the new style accel module again. This time it works. I think this will probably solve my starting problem. Havent gone anywhere to test it though.

Thanks for the response five7, if this doesnt work i'll be back. Almost got this 327 straightened out! All I need now is exhaust. That lg4 stuff is really restricting this thing.

 

Drove it last night. Starts fine now.
