When they are straight fueled is it just the cyclinder walls and piston and rings that get scored and wrecked? ie if they have been straight fueled can you replace the piston, rings and home the cyclinder wall and they engine then works?

Once you start talking $90 for a rebore and there is very few places left that can do that, O/S piston and rings just forget it, millions of PT mowers still kicking around that still run.

Here's a photo with the head off of the cylinder walls, doesn't look too bad inside. What do you guys think?

They look like score marks on the cylinder walls or are they just oil tracks? The piston crown looks smooth.

When I run my finger over the cylinder walls it feels pretty smooth

Thats good, I'd take the piston out and remove the rings gently and decoke the ring grooves. Sometimes you find a ring stuck in on one side... It will run better , new head gaslet. speedy

Ted12, If Hawthorn is in Melb and you were feeling bored and you wanted to drive to Hampton Park I can give it a hone and a new set of rings in it if you want.

Hi Norm, I might take you up on the offer. I had a bit of a look online at honing and I had a go at honing once years ago at TAFE but I wasn't 100% sure how to do it.

Hi Ted Just send me a pm if you want to come over, I'm here most of the time
