I have a 1987 Honda 200SX that I use for yard maintence.  I recently had the carbeurator worked on and when I recieved the ATV back it ran great.  After a couple months of use it will not run again.  I am getting spark, the motor turns over, I can smell fuel, and once in 20 trys or so it will attempt to start.  What am I looking over or what could be the problem.... I'm open for any suggestion!!!

Thanks!  

try to put in new plug after it has sat for a while
so you know its not flooded should work
