Yamaha stalls, sputters and backfires
After last year's annual service on my 2010 Yamaha my golf cart would stall if I let off the gas and suddenly stepped back on it again. I took it back and they said it was a clogged fuel filter. That wasn't it because it does the same thing when it is cold, or when I have been coasting or stopped for a second. You step on the gas and nothing. You pump the gas pedal and it backfires. After a run and you park it in the garage you get a strong smell of exhaust and the exhaust pipe has pitch black soot in it.
Any ideas of what the problem could be?
Thanks!
