[adw]

A lot of talk here about stale fuel and air leaks, but none about what two stroke oil is being used here, quaility,quantity.

Also a result of stale petrol, found on engines running on stale fuel but not being worked too hard.

Seizure would shortly follow if the engine is worked hard.

Not sure what oil I've been using, I'll check when I get in tonight.

 

Can I just replace the rings in it? Would be easier and cheaper to do this. I'll maybe pull it apart tonight if I have a chance.

 

Any thoughts on an air leak? How would I work out if there was one and where it is?

 

Thanks guys.

Started looking at the saw last night to pull it apart and see what the story is and I found that 2 of the 4 bolts at the bottom of the cylinder that hold it onto the head had fallen out!! So I've ordered spares and once I put them in (with threadlock!) we'll see how it goes.

Well there is one big air leak !
