Goff cart "backfiring" problem
 

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.

It's not a fuel problem but the carburetor. You can buy a new one on the internet for about 25 dollars and is no big deal to switch out ,about 25 minutes. Also,make sure the choke is not pulled out a little. Not sure about the battery needing charge,could need a new one or clean cables

Backfiring is usually caused by the throttle linkage out of adjustment or the idle screw adjusted to where it is holding the carb throttle plate open a little. What is happening is the throttle plate is open and it sucks gas in when coasting, then when you hit the gas pedal again it starts igniting the fuel causing a backfire. Suggest taking it to someone who knows what they are doing. It has nothing to do with the fuel you have in it.

Agree with the above diagnosis but have another related question. Our Club Car has backfired a few times but it is an EFI, so the above is not relevant. Any ideas what could be causing an EFI to backfire?

I have never worked on a EFI golf cart, so do not have a idea what it may be. It could still be the linkage adjustment holding the throttle body open and some how sucking fuel. When letting up on the gas pedal it needs to close off any fuel. Remember in the old days turning off the ignition on your car, pumping the gas pedal, then turning the ignition back on, BANG, if you were lucky you didn't blow the muffler off :) Your golf cart turns the ignition off when you let up on the gas pedal, then you press down again it turns the ignition back on, hence backfire.

First off, everyone is correct, its not the fuel you use.

Second- please don't buy a 25 dollar carb off the internet, they are junk.

Third, Carburetors rarely go bad, especially on a Club car. The right Tech will be able to cure the issue, more than likely without changing any parts.

I have a club car efi that will occasionally backfire. It will usually happen after I have been on a long stretch of the MMP and then let up a little. Bow’s explanation sounds reasonable...

Timing??????

My Streetrod did this several years ago. Same people told me the same thing. Car Fixer fixed the problem in no time flat. Runs great ever since. I do use premium fuel.

I have a 2018 Yamaha that is backfiring occasionally. It may not do it for two or three days and then it will backfire there or four times in one day. Has anyone had any success having this problem fixed at The Villages?

What's "Car Fixer"? Is this a gas additive? Or a fuel injector cleaner? Or a person?

When I start to backfire, I stay away from Beans, The problem Stopped Almost immediately.

Was that a funny ?????

Make sure the exhaust manifold bolts are tight.......cured my problem.

Michael is the Cart Fixer. You will see his truck all around. Site won't allow me to place numbers. Google him.
