Hello everyone,

I was driving my car to the gym where it started back firing from stops. When I got to the gym, I shut it off and fired it up and it was back firing but started. Hour or so after I come back and it turns over but doesnt fire. While cranking it made a loud "pop" and I havent done anything sense. I got it towed home and took plugs out and saw it was running lean. I have a 383 in my car and it hasnt been running well since I have no tune yet in it. I took the cap of the distributor and it looked burned a little.Any suggestions?

 

It reads like a pole piece is bad inside the distributor.

That would cause a back fire among several other items like the timing being off.

Did you lock your distributor in place when you set the timing ? It could just be out of time.

I would like to have a 383 in mine !

 

I took the cap off and the top of it on the inside it burned it looks like. While the rotor is burnt as well with white powder all inside it.

 

Here is what they look like.

 

That could be from the pole piece bouncing up and down making the rotor hit the cap causing your back fire. It happened to mine.
