The numbers and letters on the side of the engine has this TZH147FMF/70402233. I'm needing to buy parts. I have no compression on the motor.

Some photos of the engine itself would likely be helpful but from the engine # it appears to be a 47mm bore 90 cc air cooled motorcycle engine.

If I am correct this kit will likely be what you need, but you may want to measure your cylinder bore to confirm before ordering.

. Thanks James. If you wouldn't mind. I could take a few photos of the engine. It's a 4 stroke. With the starter on the bottom side

Well James. I had bought it for my daughter a couple months ago and the guy I bought it from told me it has been sitting up a couple years. So I bought it put a brand new carb on it and it fired right up. My daughter rode it for awhile started noticing it keep dieing alot. So I ended up buying her another one cause she was really alittle to big for that one. I did a compression check on the cylinder and barely get 30 PSI. So I'm pretty sure the rings are bad. I'd just like to put a whole new top end kit on it and then sell it. Cause I want need it anymore but I'll let this be Know when it was running that little thing is fast. It would carry me no problem. I really appreciate you and everyone helping me with this little ATV. If I looked correctly the jug, head, piston and everything comes in a kit. I seen on eBay. I just wanna make sure I get the right one.
Thanks everyone

You're going to have to pull the engine to do a top end rebuild, there isn't enough room in the frame to slide the head and cylinder off. Once on the bench, then you can determine which cylinder and piston to buy, after you've taken the bore measurement and check the wrist pin size.
