With everyone being told to stay home I’m starting to get a little stir crazy and the rain really does not help so did a little tinkering on the 140. I know it needs new piston , rings and possibly connecting rod but needed something to keep me occupied.
The shift guide for the hydro handle was really worn
so a bit of tack welding and hand filing work to clean it up.
Installed the integral hitch from pieces I had squirreled away .
Took everything back apart and painted all the pieces involved , misty rain made that fun outside!!
Integral fit nicely between the 24x12x12’s was worried they would hit.

engine overhaul for now, I may put her back to work and sell off a few others. I have the mower deck for it in real good shape its only a 39 though. If it goes as planned the 210 may go first but I may have trouble parting with it as good as it has been to me.

I watched a video the other day and I saw a guy replace the small cam nut in his 140 hydro. It was so worn that it creeped. Then he set the hydro creep nut and set it up. I love to watch that stuff in case I need it in the future.

My little 210 should have rings as well, when I start her up she blows white smoke for about 2 minutes. When she heats up and runs a while, she stops. Oil has a slight smell of gas as well. I just didn't want to get into that yet, my shop is full of other peoples projects.

Tore into the heart yesterday and removed the piston I was able to wobble it in the cylinder ever so slightly.
Honed our the cylinder not sure if I went far enough , will await my brother the machinist to measure and see what he says.
Pressure washed out the engine area while it’s open .

I'm curious to see since you now have the piston out if a piston ring above the oil control rings may have been installed incorrectly, upside down, on this one. I recall a while back you mentioning that there was quite a bit of oil on top of the piston and wondering if this was a possibility. You're well on the way to fixing the problem in any case, good work.

Piston is worn and was cocking in cylinder wall think it was a lot of blowby
It was not even safe to leave alone it would have melted down and ruined block and I’d like to be able to use it.
Did a small amount of porting on intake side smoothing out the castings. Removed both valves and reseated.
We will see after it’s measured.

Well took advantage of today’s nice weather and finished installing new gaskets, new rings on the piston, piston into the block, installed head and head gasket and painted a few parts . Not worrying about it being perfect. Trying not to fall into the full restoration as I sometimes do and just clean it up.
Even put a new set of grips on the bike today too.
