Sorry, I like 2stroke.time for different lubrication.

=Stumpys Customs I bout forgot to post the pics of how the P&C looked after two gallons of Klotz Super Techniplate @ 32:1. I won't be useing Klotz Super any more.
Another one of the saw without the tank.
Could this be tuning or just an oil that doesn't burn? Honest question, I'm still learning about two strokes.Thought I remembered stump seeing this too.
Doesn't everything leave carbon as it burns?Its not tuning it was out of a 562xp. My 550 was starting to do this too but not nearly as bad.
yeah but shouldnt below the rings.sticking,worn or non seated rings cause that.along with bad oil or gas cooking onto the piston sides.Doesn't everything leave carbon as it burns?
The idle of my 362C would say no, otherwise, maybe.I've never messed with a autotune but does autotune mean it's perfectly tuned all the time?
Rings stuck by continually "rich" oil mixes, or non burning oil?yeah but shouldnt below the rings.sticking,worn or non seated rings cause that.along with bad oil or gas cooking onto the piston sides.
of course the piston above isn't exactly carbon.more like sticky gum.just on the verge of carbon.that ring land looks bad.did the ring come out in one piece?yeah but shouldnt below the rings.sticking,worn or non seated rings cause that.along with bad oil or gas cooking onto the piston sides.
rich and non burning oil goes hand in hand.too many variables going on there.Rings stuck by continually "rich" oil mixes, or non burning oil?
Thanks.I think I'm starting to smell what you're steppin in.rich and non burning oil goes hand in hand.too many variables going on there.
#1 too rich either in ratio or tune.
#2 gas octane and bad oil.
#3 worn rings
#4 stopped up air filter
what we have learned in this thread
too much oil or too rich on the high speed washes the piston resulting in no carbon or gum build up
what we all know is too lean of tune or mix results in a scored piston or rings.
too much oil will lean the tune.
lean on the oil mix (too much oil) won't necessarily cause scoring.but could cause cooking of oil on surfaces
in the situation of the piston that looks like that......... my situation at least bad gas continually ran thru the saw.so bad that its on the verge of turning into varnish.varnish or super thick gas mix will still burn but turn into gum on the piston,transfers and actually coat the crankcase.last one i fixed i constantly soaked the bottom end in seafoam for a week.
