ok, under any good amount of acceleration over 2nd gear the car tends to sputter and cut out. i drive an 83 with a hollow pre cat. my buddy who stomped my *** in a crx bec of the sputtering, said that each time it pops through the exh it tends to puff smoke. my car does this alot esp. since i hollowed the pre cat. if i am running about 90-95 and make a lane change to the left my car will begin to sputter and cut out. it is annoying as crap. i know my car is better than a honda i think ive got the 20 yr old *****, ya know right a 20 yrs EVERYTHING goes to ****!

pls help with any ideas.

also, on the average, how many turns out does the mix screw sit on most stock 12a's?

also how far is the acc. pump unscrewed?

C/S why doesnt anyone run carter or edelbrock carbs everyone likes holley why?

 

The carb is running out of fuel. I'd say you either have a clogged fuel filter or a failing fuel pump.

 

A lot of people overlook their fuel filters. Both my 85-SE with 140k miles, and my 85 base model (100k) still had their original fuel filters. The Base had been sitting for 3 years, and the filter was so bad, she was almost undriveable until I replaced it.
At one point I had to pull over, and hit the filter with a hammer to knock enough crud loose to make it home.

 

yay for the fuel filter!

my problems fixed!

but, does anyone have a rough estimate on the carb settings?

 

When I put on this carb I have now, '84 Nikki on an '82 12a, I turned the mixture screw all the way in (clockwise) and then backed it off 3 full turns and adjusted the idle screw to correct the warm idle. I saw this in a couple of different posts, so a search should turn something up.
