The 026 pro I tore down was 44mm.

I'd be pulling topend and micing to make sure.

The dealer told him it needs a new piston./end quote .

Might be might not be . A piston doesn't have to be perfect to work and work well .If it's just lightly dust injested or lightly exhaust scorched you can buff it out most times .

As far as I know the 44.7 mm cylinders were only found on 260 and not on 026 . Some 260 were also 44mm thought .

I think what you say is correct . . . .

But you never know on a old saw, for if the part will fit, someone may have put it on there? It is best that it is checked for size.

I pulled spark plug and did a compression test. I got 45 but it peaked to 50. I pulled muffler and found a scored piston. I found cylinder that didnt have a good cross hatch. I saw some up and down fine scratches but nothing deep like a score mark. Also the spark plug had brown carbon build up on it around electrode of the spark plug.

So was it 44mm or a later 44.7mm?

Sounds like a easy fix then. Either just clean up piston and re-ring if not real bad scored up piston or put a meteor piston kit in with the caber rings that come in their kits.

Did you say it was straight gasses?

I dont know the piston diameter yet. I'm thinking new piston and rings. On baileys site had cast iron rings also for this saw. Any take on cast iron rings?

I dont know about straight gases.

The number one brand of after market piston rings is Caber and they are sold by Bailey's though you may find them cheaper elsewhere.

I's be figuring out why it scored before putting in a new piston.

Cant spell

I know the piston has brown streaks where it scored at. The spark plug was brown also with build up.
