Need a new piston and rings for bt100 50mm

[Thomasp]

Can I get some suggestions and links to purchase a new piston with rings? Amazon is a bust so far and eBay.. well there are several options but I would feel better about making a successful purchase with no complications with the advice from people who have been there and done this before.

I've never worked on a 80/100 but have on all other size engines, from what I've learned about your engine there should only one type piston. Everything I've read on it says it has the high pin location, the pin in near the middle of the piston. Measure yours then find a listing that has the measurements.

Thank you, I will likely buy that one. I think I will need the one with the 12 mm wrist pin. I measured it and it was closer to 1/2 inch than 3/8 inch which is the same as 10mm

That's why I said to measure yours, you can't be too careful. Like the commercial says " measure twice cut once ", that applies to this hobby too, " measure twice order once ".
