In my 72 K20....I have sent the Q-Jet off to be rebuilt by the 'Best Guys In Town' .....three times now
and it still isn't right. Maybe I am missing something really obvious here...let's see if you guys can find it
It seems to run dry if it sets overnight...you have to crank it over a while and pump the gas before it decides that it has enough fuel to start.
Once you get it hot, you have to hold the pedal all the way to the floor to get it to start again.
When driving down the highway, it gives up at random times, but will restart after it sits for about 5 minutes.
It will die randomly when idling at a light.
The high idle will 'stick' at times, it just takes a tap of the pedal to get it back to normal.
I am about to jerk that dang gas burner out and stick a Cummins 5.9 in over that damn Q-jet.....I don't have the time or $$$ to do a Cummins swap right now and the motor is plenty strong.....any ideas what to do with the carb before I lose what's left of my sanity?
oh, and last time I took the whole truck to the carb shop....on the way home, it backfired (rapid fire- bang bang bang bang!) ...so badly a carload of bangers drove off of the highway into the grass....now, that was really dang funny, but it was freakin' irritating at the same... time
