Went back to page14 to get this many.:rock:

I sent some rep back your way my friend. :msp_thumbup:

Bad move, I tried that and he just filled all the empty spots with JB weld. I told him that he couldn't make an airfilter out of that stuff, I think he took it as some kind of challenge.

The piston rings are tough to make from JB Weld.......but we did it. :cool2:

Well, the pictures were a little deceiving.

The parts that looked like they had been polished to a high shine actually weren't, I think it must have been the flash that made them look like that.

The parts that looked like they had a 14 step, custom tri-tone, faux finish that was actually dirt and baked on, caked on, stuck on crud.

Also, were it looked like the saw was an awesome, cutaway display model.....well, that was not entirely accurate, either. Turns out those holes and pieces that were missing were actually not historically correct for that saw.

I'm sorry for any confusion and for stringing everyone along.

You should be sorry......I'm proud of you for finally coming clean and admitting your many faults and trespasses here in front of God and everyone. :D

After checking the compression even with the popup piston someone has made it was only blowing 155psi. So we went ahead and cut the squish band flat and shaved the base a little. That raised it to 185psi.

So on together it goes.......

Hi: Some quick questions: I've never rebuilt a 2 stroke before. When you shaved the base, did you have to ridge ream the upper end of the jug? And what did you use to shave the base? Machine shop tool or something else?

Thanks.

There's no ring ridge in the cylinders of these engines, as they have chrome or nickle plated bores. There were saws made with steel/iron liners, but nothing made in the last 30 years or so.

Well that makes a rebuild a lot easier! Can the bottom of the jug be shaved home-style (like rubbing on emory cloth laid out on a flat piece of marble or glass), or should it only be done with a milling machine or some other shop tool?
