I have a rebuilt Oldsmobile 350 in a 84 cutlass. The casting numbers from the motor say it is a '68-'70 according to 442.com. The motor has a brand new HEI distributor. The engine is not on the computer. It is basically stock except for a little comp cam, and an edelbrock 600 cfm carb. The motor only has about 100 miles on it.
The car runs fairly decent when cold. When the motor warms up, it runs bad and acts like it wants to die at an idle. It will drag really bad when trying to start it. Then eventually it will start up, sometimes. My guess was the timing was off, but i checked and it is set at 20* @ 1100 rpm with the vaccum advance plugged off. Is there any other timing setting that works better? Advance it or Retard it any? Or if not, what could the problem be?
