piston rings

hey all. pedro here from ocala, florida. i have a question and hope that some one here can help. I was doing a total engine tear down, and when i was trying to put the cylinder head back on it would not go. That's when i noticed that the rings from the pistion were kind of sticking out. Well i was trying to get one of the rings to fit more snug on the piston and ended up breaking it. does any one know of a place locally that i can get a replacement ring? and what size i need? i need help asap

I would help to know what type of engine you are running

it is the 66 cc from boy go fast

Just a cautionary note for when you do get new rings: Did you line up the end gap of the piston rings over the alignment pins in the piston's ring grooves? If not, the alignment pin will keep the piston ring from seating completely in the ring groove.
The alignment pins are there to keep the rings from rotating around the piston.
If allowed to rotate, the open ends of the rings will snag on a cylinder port and ruin the engine.
