Default Backfireing Golf Cart

I have a 2015 gas Yamaha golf cart not efi.

After running about 20 minutes it backfires when coming to a stop after going down a hill into a tunnel or approaching a red light.

I bought the cart used (remanufactured) and it is still in warranty.

I had it back for repairs 6 times and the problem still exists.

HELP

#1 cause: The throttle plate in the carb is not totally closing when you get off the gas.


Since you purchased a used cart, I'm guessing this is it.

On my 2010 Yamaha I found that the connection between the expansion chamber (muffler) and tailpipe was not air tight and would back fire. On mine the original connection hardened and shrank even though there were strap clamps.

Just had exactly the same issue...Willy’s came to fix...the hose between the muffler and the tail pipe had come off or broke. New hose, 2 clamps and problem fixed. Easy DIY fix. Had Willy do an annual while he was there.

I find it hard to believe that a missing piece of heat resistant rubber hose would cause a backfire. Maybe

My Yahama was backfiring after servicing which included installation of a new spark plug and when I drove it it backfired. Had it looked at and found there was almost no gap on the spark plug. He gapped it and no more back firing.

My guess is that you or someone has opened the governor to gain speed. This dumps more gas in the engine than it can process so the gas builds up in the cylinder when you take your foot off the gas resulting in explosions known as backfire. Eventually this will destroy the motor.

Since it is carbureted the most likely cause is the carb itself. It sucks in too much fuel when deceling and heat fires in the exhaust.

On April 2nd 2018 an irresponsible golf cart owner that failed to maintain their golf carts changed my life forever. I was just leaving a golf cart tunnel when a golf cart came down a hill and had a tremendous backfire about two feet from my left ear. The backfire has caused permanent tinnitus (for those of you that don’t know what the is, look it up). The loud ringing in my head is 24 hours a day and the only way to get any sleep is with medication. In addition the blast caused nerve damage to my left ear as well, making it necessary for me to take pain medication to combat the pain. Be responsible and fix your dam carts before you ruin someone else’s life!!

It sounds like your accelerator cable is to tight. Coasting down the ramp your foot can not touch the accelerator pedal.when you touch the pedal it should not immediately try to start, there should be some play in the cable. If cable is too tight it pumps gas in cylinders even while coasting.
