i recently flipped a 1995 kodiak and ive been having problems ever since when i start it up i wont stay running and it contsantly "pops" wen its running and air shoots out of the carb i changed the spark plug and still have no luck any advive would be appreciated

 

Here's my opinion based on the little information you provided.

The carb may have sustained some shock damage in the rollover and the float may be causing a low fuel level in the bowl or some junk got dislodged and is restricting something.

Worse case situation is damaged valves due to immediately starting it after it was upside down.

My dealership's service manager said that the natural instinct to get the machine up and started again right after it's been upside down is risky because all the oil runs to the top of the engine which drains the crankcase and fills the oil galleries in the head, etc. It's like hydro-locking a engine after stalling it underwater.
