Hey guys, looking for a small engine mechanic who would be willing to take a look at my motor. I have a 92' model Onan Performer on a longtail frame that has been surging. I already took carb off, cleaned and rebuilt it then put back together. Ran fine after putting back together. Well that lasted one fishing trip then it started back again.

I am somewhat mechanically inclined but this is over my head now. NEED HELP!!!.
