1650 is burbling and backfiring then dies
 

I was out plowing snow with my 1650 today and it started burbling alot, then backfiring, and then it would die. It ran perfect the last time I had it out so I'm a bit stumped.

Might start with checking the points, make sure they are not burned. Condensor? Getting good spark? When my 1250 acted that way this past summer I found out my coil was bad and that the plug wire was bad. Just some ideas. I am sure some of the other guys will have some better input.
