Hi all, I have china 66CC engine, and while riding about 28 MPH i felt a small tug, then the engine lost all power, and died.... I tried to restart it, and it felt like low compression as the motor turned over a little easier then i remember. I pedaled home about 3 miles, and decided to take it apart to look for damage. I did not have to look far! So I have a new cylinder, piston, and gaskets to hopefully get up and running again. I only have about 232 miles on this bike and has been mostly trouble free. On another note, what broke? The only thing is seen was a little broken spring holder for the piston, (See picture) It seems like alot of damage for such a small piece? What are your thoughts on this? The bottom end is still tight and moves freely. Note also that broken spring piece was sitting on top of piston when i took the head off...... Thanks!
