I did notice at full throttle I get a backfire. How could my timing be off if I found tdc and it started right up? Any fixes for my problem. Thanks
Your timing is likely off a tooth or two.
When the #1 piston is at TDC, the rotor inside the distributor needs to be pointed directly at #1 plug wire terminal on the distributor cap.
Make sure you are at TDC on the compression stroke.
Otherwise you could be 180 degrees off.
Once you are sure you have it installed correctly, then time the engine with a timing light.
Don't forget to remove the spout connector when you are setting the timing.
If you don't, it will not work properly.
