Last summer after my annual Street rod checkup it immediately started "backfiring" especially when I slowed down to enter a tunnel. When I called the service company I used he told me it would disappear. Then weeks later he told me to put in high test gas. I don't use it often and had still lots of gas in it, so I just topped it off with premium. When I called again he said I might need a new carburetor. It took until last month to use up that tank of gas. No luck.

It also is having starting problems after sitting even over one night and needs a charge. I can start it after a few tries only going forward so I now back into my garage. Is that related?

Any advice out there would be appreciated.
