Last night before bed I scanned the local classified adds like I often do.

Found an Add for what was described as an Olympyk 100cc chainsaw for $50.

I contacted the guy and he said he wasnt sure what it needed but he thought maybe a piston.

So I raced over there this morning and met the guy. Nice fella, bought this sawnew in 1998 from a local dealer.

He said he never used it much but did some milling and blocking with it. He said he had no clue what it needs but he thinks it needs a piston..

Saw is in great shape, it still pops when I pull it over so well see whats what when tear it down.

Heres some picks, came with a 26" bar and stihl chain.

IllI bet parts are going to be hard to come by but for $50 I figured Id roll the dice.

Maybe a 395 piston can be made to work if it comes to that???

Anyhow I suck for sure!!

Any help as to where to source parts or wether anyone has stuck a 394/395 piston in one of these??

Cool saw for sure.
 
Nice score -

A 395 piston could be made to work but the main difference is that the 999 piston is domed and the 394/395 piston is a flat-top. The 395 piston is
also a little taller, so you would need to get the 395 piston machined down or use a much thicker base gasket. The 395 piston skirts are also
longer. Another difference is that the 999 piston is a full-circle piston and the Husky piston is not. So you would need to make sure the 395
piston skirts adequately cover the ports in the 999 cylinder.

Thanks for the info. I have a lathe so if needed i could go that route.

Tore the saw down. Needs piston for sure.

Fuel line was split, so the story the guy told me was correct. He said he was milling and the saw seemed lean, he kept cutting and the saw bogged and shut off..

He said he pulled the spark plug and he could see scoring.. so he put it on the shelf til I just bought it..

Cylinder is fine, little smear under the exhaust port but nothing major.

The piston is scored, rings were stuck, otherwise this is a low hour super minty saw. I'd love to get it running again..

You could buy a Meteor 395 piston kit and machine it. If it were me, I'd machine the 395 slug for a pop-up, since it's not going to be
a domed piston. I think I may have a junk 394/395 piston I could send you for using as a mock-up.
 
I'll probably buy chinese piston for messing with and a meteor piston for the final assembly.

This saw is super super clean, its worth fixing for sure, even if a piston is spendy.

Maybe I can find a piston in europe for this thing. Have ro do some research.

My buddy is an aircraft machinist with cnc capabilities. May farm out the piston machining to him if needs be..

This will be a fun project..
 
yeah..YOU SUCK!!! you could part that ***** out for probably about 400.00!!!!

Figured the bar was worth the $50, the stihl RS chain is for sure.

This saw is so clean, it would be a shame to part it out.

Been looking for a big bore saw for awhile so I'm really glad to have this one.. Neat to run sometjing different.
 
been a while,,but I believe they were about 80....

I'm searching the internet trying to figure out who I can even buy one from.

Up here in Canada there isnt many efco dealers.

I emailed the shop that this saw originally came from, they are a big small engine parts supplier in my area, maybe they can hook me up.

Might contact oleo mac in italy
 
Got some feelers out looking for a piston, I contacted Oleo-mac on italy and they said they will get back to me.

On another note, if I cant find a factory piston what about a 298xp piston? That one has a full skirt but I'm not sure about the wrist pin size? Anyone know??
 
Well I'm off this week so I got up early and did some more work on this saw.

The good news is the jug cleaned up really nice. Its almost perfect just a fee more little transfer stripes left and its perfect.

I think I may split this bottom end. It was super dirty and filled with seeds and crap. I rinsed it out couple times and lubed the bearings with oil.

It turns smoothly etc but I think I can feel the slightest up and down movement in the pto side bearing. Its ever so slight but its there.

Pto bearing is a 6303 C3, pretty common.

Both seals are the same, they say 15-30-6/6.5 on them. Im guessing thats a 15x30x6mm seal.

Not sure about the flywheel side bearing. Feels perfect but if i do 1 side I'm doing both.

So I guess I should split this thing and figure out what the flywheel side is. Maybe take the bearings to a bearing supply house and see if they can find me bearings and seals.
 
Well the cylinder cleaned up nice, got a tiny bit of transfer left.

Started with this:

Now looks like this:

Heres a shot of the seal number, guessing its a 15x30x6mm?

Anybody know the flywheel side bearing number?

I used a 395 piston in the one I built. I think I was able to run it without the base gasket and no machine work, squish ended up around 0.030". Not the best solution as the flat top piston is not great for a squishband that is designed for a domed piston. I later cut the squishband flat and ported it.

Here was my build thread.
