running rich maybe? timming?

also make sure all spark wires are on correctly. Most likely timing.

Normally when a header glows red then the engine is actually running rich, not lean. At least i think so anyway. It could very well be the other way around.

Keegan

how do i adjust the timing and richness

Latin270

If you didnt mess with the carb and it ran fine in the car u pulled it from then I wouldnt mess with trying to "adjust" it. Check the timing 1st make sure spark plug wire are in order then check the actual timing mark. Did u remove the distributor??? or was this the original that was already on the running engine?

hay where in oregon do you live?

you need a timming light to set it correctly

well if your facing the spark plugs
in the center of the carb just above the spacer there sould be a philips screw with a spring just wind it in tight then back out 3 1/2 turns and play with till ya cars just runnin but you really need to do the timming first

if it's only happening on the rear rotor, then I would suspect that you might have a bad leading sparkplug or wire. If it was on both, then I would look at timing (too far retarded).
