Changed plugs and wires and got firing order wrong at the distributor initially, checked your forum, then got correct order, I think. Now I have little power and repeated back-fires. Any suggestions, kind of stuck where I'm at, literally!
Thanks in advance!

Good afternoon,

I attached the diagram for the cylinder location and wire location below for you.

If you have the firing order correct, I would check the gap on the plugs to be sure they are correct.

Inspect the inside of the distributor cap as well for any cracks or carbon tracking. That will also cause a backfire.
