Thanks all, I'll give it a try. Fpete

Thanks, Where do you have your needle clip? Fpete

Does anyone know where I could get a 22 pilot and 135 main for the Beta 300 with theCV carb?

Has anyone found a fix for the oil leaking from the head of the Beta 300's. Mine continually dribbles from the cover to the cam chain bearing cover and the head gaskets.

Blue spring, 115 main and the needle clip up one from stock. Works great!!!!

Thanks all! I already changed to the lightest spring (4th, blue) and will try a smaller jet and let you all know how it goes Pete.

Has anyone changed the jetting on the evo 300 4t. Mines runs fine at low-med rmps but will not rev out and is producing black exhaust. At high revs it cuts out then revs up then cuts out etc. but never smooths out. I installed a jetsie air screw but it does not change the high revs. The stock main is a 120.
