I have a GO 3ptR in my truggy. I have been having strange erratic tuning issues latley. pOP SOUNDS ,BACK FIRES, ONE MINUTE IT RUNS GREAT THE NEXT IT FUBAR. I unsrewed the needles to check it out and found what appears to be plastic threads from the carb coming out like little curly cues? I don't want to look back through 600+ posts.I was wondering if carb issues are a noted problem with the GO engine and what if any are the solutions.Anyone have a good carb they would let go for cheap? I ripped down the engine and everything else seems to be in very good condition.
