I finally got my parts for the cheapo 350 that I wanted to pay around with. One thing I noticed was that the base screws were loose and the case was leaking. Sure enough this had been taken apart and put back together with no sealant. No wonder the piston burned up. I did replace the crank seals and carb boot. I used a steel clamp on the new boot. I opened up the muffler on it. I fired it up on Friday, set the low jet and the high jet on the rich side. Now I'm waiting for a little bit warmer day to try it out in some wood.
