Feels great! Threads are good! He thinks it was a masonry chop saw that was going to be a chainsaw. He tossed all the parts over the years. So that would make it a K case.
It may have, I just finished cleaning the case , there was red mud in every corner!
The crank spins pretty smooth so I am up in the air about changing the bearings. It was a masonry saw so those bearing may be worn. I am soaking inside the crankcase with mineral spirts overnight just to see any crud that may be inside.
that case itself is in pretty good shape, but with its known history, new bearings, seals, and a new o-ring under that bushing would be a good idea... possibly consider a new bushing as well... any silica in there .... might have done bad things
If you only do one thing make sure it's put a new bushing, oring and seal on it because I guarantee you it will leak just enough to drive you crazy trying to keep it tuned.
Changing the bearings bushing oring seals gaskets New chain brake cover metor piston, ring. Air filter cover,bar chain air filter fuel line and filter and what ever else it needs
So I split the new case , after cleaning everything up and comparing the 2 cranks I am not using the K case crank. It feels good but between the two cranks the 371 crank is much better, alot less play in the rod.
Ordered piston bearings and seals and gaskets, new hd air filter cover and filter and rubber intake manifold and a bunch of other parts now. I need a wrap handle and a nice rear handle tank assy.
i have, i think its fine. don't have much hours on it ...but I don't see anything wrong with them. you might want to swap out the fuel cap for a nicer one, but otherwise .. ..throttle works fine
Cleaned parts today, what do you guys use to clean the fins on the cylinder?
Brought the flywheel to the welder and he is going to put a a small build-up on the fin where the pawl hits the flywheel, just a little bit broken of, he doing it n/c. He told me to drop off the old cases since I bought the others from him he would fix the break when he is doing a mag job. Nice guy I have to say.
So new parts are coming in: so far, rear handle tank, gaskets,crank seals. The welder called me and the flywheel was done . So I picked It up and filed it smooth and put the pawl back on.
Well a pile 'O parts came today so I guess there is no excuse but to put it back together! Since it started life as a 371xp I can get the sticker kit from "chainsawr"online store.
