82 350 spiiting

Asked by Kari Nov 11, 2016 at 04:28 PM about the 1982 Chevrolet C/K 20

Question type: Maintenance & Repair

Recently bought an 82 k20 350 with "carberator"
problems. Rebuilt the carb, replaced the plugs, set
the timing. Cranks right over and idles like a champ
but runs like absolute junk. At a lose at this point,
do I buy a new carb? A distributor, all new wires?
Help please!

I would first double check the ignition timing. Spitting or backfiring indicates that the timing is way off.

Make sure the right spark plug wires go to the correct plugs.

Not computer controlled, new electric choke, haven't done anything with distributor. Guess that will be next on the list

Replaced the vacuum advance on the distributor. Wasn't allowing the timing to advance. Seems to have fixed the problem. Running like a beast now! Thanks!
