Backfiring Golf Cart
 

Have had a cart since 2010, and have never had a backfire happen with any cart. Cart was serviced 5 weeks ago, by guy I have used for better than 3 years.

I always buy my gas at Gordon’s. But for the first time I was extremely low on gas, and stopped at 7-11 on Monday. Filled tank that had maybe a gallon left.

Today while driving just as I was entering a tunnel I heard an extremely loud backfire. Since a cart was coming out of the tunnel I just assumed it was theirs. But couple minutes later backfire again, I am the only cart on the path. This continues on my entire trip. So bad gas!? What to do to correct this?

Thanks
