that does sound like its going to be a lot simpler than you first imagined, good luck ken, hope its something easy to fix.

Part of me still thinks its the reeds

Well had the carb off with reeds in place I've pushed the kick start down repeatedly and noticed the reeds don't open 1 bit and there covered in petrol.

I belive Rings have worn, piston top is black as to be expected but there is only what I can describe as burning to a small part of the edge of piston on exhaust port side.

No loose bits of metal or anything!

Must admit the piston and rings I bought where cheap.

I've snapped my 12mil spanner so couldn't take the cylinder off but I rubbed my finger around in there and couldn't feel any scratches etc....

What you thinking then? New reeds and rebuild the top end?

Doesn't sound too bad!

Rings had snapped its not in best of shape and I think the bottom end needs stripping
