During the last ride my 2000 kodiak just quit. It was running great till it backfired and stopped.  It acted up the ride before that but I feathered the throttle a bit and it took off again.  I took the carb off and blew out the jets but it still wouldn't start.  After two days I tried again   and it ran when I choked it then it reved and now runs as if nothing ever happened? I am at a loss and can't just take it out for fear it will quit again.  Anyone ever had this problem???
