Hi need help on a problem. I have a 365 husky with a tar coated piston and jug useing good and fresh gas just left with alot of questions
Are you using crude oil as fuel?
He could be using outboard motor oil, which can leave a sludge. Also, certain types of old dirtbike mix with Castor oil in it will leave heavy build-up.
its called coking, and is caused from old fuel that burns too slow/cold
Without pics.......who knows!
Symptoms, tar coated.........oh sounds familiar......TCW3!
Sticky, tar coated.....mixing fuel/oil in a pop bottle!
See alot of stuff.
jred oil used to say it met the tcw3 standerd
Ya, mixing fuel in the wrong kind of plastic bottle is bad, can react with the fuel, and you get that crap mixed in.
I've seen several people around here use 1 gallon Milk jugs for Gas jugs lol. I just shake my head.....

i could be wrong but i don't think rpm's has anything to do with it.

Hi parrisw
In reply to your question no I do not use crude oil for my mix. I was uesing stihl brand two cycle mix at 40:1 in my husky I know with out pictures its hard to guess what the piston looks like .I will try to describe it as best I can .The piston is charcoal black its sticky tar like substance even acetone has very little affect on it. Brake parts cleaner good luck, gumout carb and choke cleaner just a little bit .Im down to useing liquid wrench and steel wool fine grade to get the tar like stuff so here I go thanks baotman:msp_unsure:
