I even did research and found the mantua model in united kingdom where they sell the ops motors and probably where got nitro gets his stuff and all there motors use the same carb. I do know that this issue has hurt the radical market as I talked to alot of racers and they dont like the motors for that reason.
same here, using the stock carb can get frustrating sometimes to tune. Now I'm using a nova carb and now, its tune once and forget about it. Runs perfect every outing. Really an awesome engine. Getting my third one soon.
