My project coach, which i'm trying to only keep running barely, the engine isn't running the best,
started backfiring though the carburetor, but the engine starts up easily ?
(it started doing this after i parked it from a 1 hour drive)
it has a newer distributor (Hei) , i suspect the timing is off, but the mark has fallen off the front of the engine, so idk how to check that, other then that, i've pulled the cap to make sure there was no moisture under the cap, i did pull a spark plug and it was black, which would confirm the incorrect timing.

I plan on replacing the plugs, wires and cap. would there be any suggestions at which brand/model to use ?
and any suggestions at where to look for the reason for the backfiring though the carb ?

Thanks David

Oversteer is when you hit the wall with the rear of the car, understeer is when you hit the wall with the front of the car. Hp is how fast you hit the wall, and torque is how far you take the wall with you when you hit it.
