engine problems need help

[speedy66]

ok the problem started out as the motor was running hot and dieseling upon shutdown.. occasionall backfire when it was cold and i tried to punch it..It was also not really going until 2krpms..I replaced the points with a set of accel points, new rotor, plugs.. etc.. its backfiring through the carb..'

I need help

 

[Jonstantine]

when did this start? just out of nowhere or when/if you changed something?

power valve

If it was a Holley Carb I'd say it was the Power valve on the Carb, but I don't know much about Edelbrock Carbs.
Find out if you have one on that Carb and if so it may be Kaput.
It's an in-expensive part.
When blown (at least in a Holley) they make the car run VERY rich, and bog until they get reving, and all kinds of other bad running problems.
good luck

It started out of no where..

 

[speedy66]

my biggest problem is the diesling.. what causes that?

 

[LMan]

dieseling is usually a timing issue. Have you checked your timing?

 

[speedy66]

timing is at zero on the dampner.. plus the cam was set straight up..

My thinking might be the carb.. it seems to surge while driving..

 

[jesserose17]

timing is at zero on the dampner.. QUOTE]


I would set the timing to 10-12 degrees BTDC.

 

[LMan]

your timing should NOT be at zero. Follow jesse's advice and let us know how it goes.
