I have a 2strok 66cc that has been brokin in for a while and the only prob. I have is that I 4strokes at w.o.t. and I've tried moving the clip and playing with the screw on the carb and nothing seems to help...any idea
I have gone down to .024 and still it is running rich (32:1 ratio), if I go down much smaller will just starve out or will it burn up because of not enough lub? Sorry, I kind of jacked the thread...It is your main jet its too large you will need to make it smaller I show how to do this on my sticky posts somewhere. I do not know of anyone selling different size main jets right now.
soldering shut and re drilling the main jet is easy if you have the tools to do it with. find out the size first then go one size smaller.
stock is usually 0.70mm so the next smaller would be 0.65mm.
that size is around 0.026 so the drills are going to be very small and you will need to use a pin vice which is a hand held and hand powered type of drill bit holder. You can get these pin vices at most hobby shops and maybe even the micro drill bits.
If its running rich then you need to lean it out unless something else is causing it to run rich like a sticking float.
