Forgot the piston

@mdavlee

Your rite, it is the super techniplate, and I didn't run the saw too much after I started using the Motul cause I got my 660 and the 029 was running awfull.  I thought I may have been a little lean on the tune, the spark plug tip was  a lite color, sure looks rich on the piston though and the black is sticky/gummy also. My 038s done the same thing only not as bad, rings didn't stick. I thought the rings might be leaking the exaust by them? When I rebuild it I'll go back with Caber.

You seemed to have spotted the techniplate oil right off so maybe it's not good in saws.
I just thought it might lube better milling.
 I've went through allmost a quart of the Motul 710 in my 660 at 50:1 I'll pull the cylinder and check it. If it's like this I guess I'll just run stihl oil. Any advise is appreciated, milling seems all together different on the saws than firewooding

You think at 50:1 it ran hot and heat caused the piston to look like that? I don't see any wear, the first time I tore it down it was just as bad, when I got it cleaned up it looked fine, ring gap was same as when new, machine lines still on piston, maybe the cylinder an piston was a dudd, when I got it the impulse line connector was missing from the cylinder, had to rob one from another cylinder. I'll run the 32:1 don't mind at all, I don't want this to happen to my 660 or even the 029 for that matter.

I had the other Klotz. Allmost afraid to do any more milling till I find out what the problem is or was? Maybe my tuning, When I set the high side, I set it so it would 4-stroke untill I put it in the cut and cleared up, when I set for milling same thing and then turned out maybe 1/8 more. I'm not doing something right though
