Yesterday, I tried to finish cutting up the trees they dropped last Friday. I was using my buddies Husqvarna 435. Ran it for about an hour, shut it down to get a drink and came back to it locked up. I thought it seized, so I tore it apart. The fucking crankshaft bearings are just supported by the plastic housing!
There's no metal support. And one bearing overheated and melted the case, cocking the crankshaft, binding the flywheel to the coil pickup. Plastic crankshaft support....
. I shimmed it with some aluminum and copper flashing and got it running true within a couple thousandths of an inch. Should be good enough. I really wish I had access to a lathe and miller, would make repairs like these much easier.
Because of this I pulled out my seized Husqy 350. It's got a full metal case, not fucking plastic.
I'm looking into a big bore kit, bigger carb and a tuned pipe. A little port work and it'll be a nice little hot saw. For less than a new one. Vroom, vroom, gotta love a 2 stroke.
