Re: 100:1 Mix
Tom, It took about 10 miles of riding before I really noticed my engine smooth out and run better. You should pull your plug and look at the top of your piston. See what color it is. Yours may be fine but one of my engines was a sticky black mess. After a 12 mile ride it had cleaned the top to a pretty gold color.
One thing you will probably notice is increased R.P.M. and speed at WOT. It will sound like the poor little Chinese engine is going to blow. I hope mine doesn't. 35 m.p.h. is waaaay to fast at our age.
