Howdy again,
this is a 51 gmc 228 motor...
everything has been replaced 15 months ago, wires, dist. cap, plugs, carb,
fuel pump, etc.
Truck has set up for 15 months...
I have a miss in the motor...
cranks up just fine,
but misses and back fires is you try to drive it...
vac advance appears to work, since it pulls on the dist...
good compression...
plugs look good...
I don't know where to look next...
help, help
