Re: Backfiring
Backfire can be cause by lack of fuel. check the entire fuel run from inside the tank to the carburetor, and then inside the carb at the filter and the float.
I had that happen because an extra gasket was stuck inside the small glass bowl filter.
If you get too many big backfires then your muffler will split open at the top where the seems are, and then you will get perpetual backfires. I had to replace my muffler because of backfires, but that turned out to be a good thing in the end.
If you are backfiring when coating down hill check your timing, you may be way advanced.
But really look for a leak in the exhaust. With the car running put you hand just above the muffler (if you have a heat shield along side the space), do you feel exhaust air? Replace the muffler.
These all happened to me.
