Now if somebody would just throw together a quality after market piston and cylinder for the 020/200Ts it would be a red letter day . :)

Well that is nice to know because the 020/200Ts that didn't die from a fall from tree got killed off by a lean run that cooked the top end .

Flea bay is full of complete crankcases that obviously came from fried saws .

Thanks for this great info!
I don't have the seal removal tool I have seen on youtube - can I go ahead and try to flick / prise  them out (using something like plastic that wont do any damage to the case) or is the tool required?
The crank also is not so stiff to turn over now with a little lube - looks like part of it slightly brushes one of the bearings as it rotates.
Has anyone bought gear from Hutzl on ebay? I'm considering a piston from them (and a kit with the seals and new gasket) but I'm wondering how they can make the stuff so cheaply! I guess there is not too much to loose though seeing as it is so cheap.

Hutzl is in Hong Kong

I'm looking at aftermarket p & c's for this - does it make a difference if the cylinder is nikasil or chrome plated? Is a different oil ratio required for chrome?

Probabley not .The term "Nikasil " is basically a trade name for a plating process patented by the Mahle company which uses an alloy of hard nickle with certain additions of an amount of carbide .Hard chrome if done correctly most likely would work just as well .

Some after market kits are well made and some are not .As for oil use whatever you want just tune it rich for a few tanks after reassembley and start up .After the initial ring seat lean it up a tad bit and run it like you stole it .It'll be okay .

I just wanted to say a quick thanks for the advice people had provided for this project.
The saw is back together and running strongly. In the end, I put in a new piston, bearings, seals and fuel line in from Huztl. The quality of the parts seemed OK. The new piston did seem to be a little heavier built than the original, though I guess that has to be better than too light.
It definately was a learing experience having the saw broken down into every individual piece, and now I'm looking for another one to do it again.
I'm pretty happy with the end result, but I can't say it runs like a brand new one. It does a funny thing where it idles perfectly as long as I'm holding it, but if I put it on the ground, it idles fine for a few seconds, then the revs drop, it starts to vibrate, then the revs pick up again. It keeps cycling like that until I pick it up again. In the two tanks of fuel I put through it, it twice stalled without warning when idling with the bar pointed at the ground, but re-started easily when horizontal.
