I went thro a lot of water my 220 bayou stopped running I got it started back and now it is backfiring and has no power how can I fix it

first I'd clean the carb, new spark plug. I've seen a bad cdi cause that but thats the last thing I'd check cause $$$

a large hammer and lots of effort. if the center has come out you can cut the outer ring with a dremel cutting disc.

could be lots of things. you'll need to clean the carbs and the whole fuels system too. see if you're getting spark. if the motor sucked in water it could've be done for also.

Sounds like carb needs to be rebuilt. Could possibly be water in the gas.

T is usually the mark on the flywheel and there's usually a mark on the cam sprocket and head to line up. you can google up a service manual too most likely.

buy a bottle of gasline anti-freeze. it will absorb any water in your fuel. add a half a bottle now and a half next time you fill the tank. should improve the operation of the engine

have the voltage regulator checked for the proper output

On the Bayou 220 you have 2 wires from the Ignition Switch. If I was you I would wire them 2 to a toogle switch or push bottom start.

ok buddy to stop the back firing on the carb will be a screw turn this in 1/4 of a turn and try this the mixture screw on pic below

When you filled with new oil, if you changed the oil filter, and the oil was at the top third of the inspection window after you started it and then shut it off, the oil level is correct. When you start the engine the oil is being pumped to the top of the engine and through all of the oil passages. That is why you can not see oil in the inspection window while it is running. Make sure when you are checking the oil through the inspection window the vehicle is on a level surface and you have allowed enough time for all of the oil to drain back to the crankcase.
