I have a 036 with a scored piston that I would like to fix up. After trearing it down it looks like it has a aftermarket piston. I have read as much as I can find on here about trying to save the cylinder. There is some light streaking above and below the exaust port that I can barely feel with my fingernail. I plan to try to use the acid process I read about on here.
My questions are the the following;
1. Do I have to hone the bore with a ball hone or is hand sanding with 320 grit ok?
2. Can I use a used Stihl piston and rings(ebay) or should I buy a new aftermarket($28 Baileys) or new Stihl(?? $$-probably expensive)? I can't find any aftermarket piston/cylinder kits either.
3. Can I safely eliminate the base gasket and use Yamabond to seal without checking the squish height?
4, Does Stihl make a dual port muffler for this? If not how do I open up the muffler?
I bought this saw last spring (it is super clean - I paid $325)and the guy said he had just replaced the piston but the cylinder was ok. I did not run it much until last week and have only run 5 or 6 tanks of gas thru it . When I pulled the muffler I saw the scoring on the piston. It still runs Ok but is hard to start(20 plus pulls cold).
Thanks in advance for any help you can provide.
