Polaris_Is_King

Hi every one, I have a 1994 Polaris XLT, I cleaned the carbs at the begining of the year, and it ran and rode great. Then one day I noticed that it wasnt firing on the left cylinder. So I replaced the plugs, it didnt really help. It started rightup but would bog alot and backfire when I let off the gas. So I drove it home and put it in the garadge. Now it will start but only run for a few seconds(idles down till it dies) and backfires LOUD after a few pulls.

Anybody have any ideas on what could be wrong? Or have any advice?

Thanks a bunch

big shot of water, maybe.

Clogged carb, water in that carb, or gas is no getting to that carb. Shut the fuel off and drain all of the gas past the shutoff ( in all carb bowls). Clean out that carb and put back together and hope for the best!

Not sure, but to me it sounds like you might need new rings on the pistons. Oh and have you bin keeping the oil at a good level because if the oil gets low the cylinders and pistons can get scratched.

Start by pulling the fuel line off and pull it over and see if the fuel really spurts or just dribbles?

If nothing comes out pressurize the gas tank either by blowing compressed air into the vent line or blow air into the opening with your mouth while the lines are disconnected. Gas should come out. Now pull more until it continues to come out

If you blow into the gas tank, be careful when you take off the pressure. It is liable to blow fumes back into your mouth. That is the foulest tasting thing ever, and if you will become dizzy if you inhale them.

Close your mouth and plug your nose before letting off pressure. It will blow fumes at your face. Suggest closing your eyes too
