Hello Bill,

Thank you for your prompt reply.

From my description of the inside of the sleeve; Shiny, smooth, dark surface, not the silvery shine I expected to see. No "step" above the piston travel, no scratches, no peeling nickel; can you conclude something?

Is it not supposed to have a metallic shine?

This is my only ABN engine, so I don't know how to identify when it is worn. In ringed engines there is a definite "step" above the ring travel and I never had an ABC engine wear out on me.

So please tell me what I am supposed to sense, when my 46FX's piston/sleeve set needs replacement.

I was told it would not idle, would not accelerate, would give low power, low compression... Now compression is low only when the engine is hot, but even then it is still enough to hand start.

Sincerely,
