I hear people posting about modifying your jet,well what does it acually do?,and is it hard to do.what are the thing you need to modify it?....Thanks for you time guys....Randy
I bought my 66cc engine about 5-6 weeks ago and it has the larger main jet. I think that previously they were 0.7mm and my stock jet was 0.79.The new NTS carb comiong out for the 66 motors claims a slightly larger jet, and justmay wait until I eventually get one of those.
Drilling a jet is a terrible idea. The swirls from the drill bit make the fuel swirl which actually slows movement through the jet and will just upset the mixture. Buy a new jet for a few dollars.
