Default Piston Stuck

Well it seems my dad left some fuel in his engine and it gunked up and jammed the engine. So i was wondering what are some safe ways to free it besides taking it in which ill probably end up doing anyway but is there any ways you can do it besides that. Umm its a Losi XXX nt sport.

any help is appreciated

try soaking it in some marvel mystery oil over night. me and my lhs owner tried this to an old O.S. motor that was gummed up. it actually worked. dont know if anyone else has ever tried this. first time i'd seen it done.

Take the backplate off and put some after run oil in, let sit for a few hours or over night (depending on how bad its gumed up.

Most likely the bearing are gumed up and the oil will loosen it up.

the marvel mystery oil will work alot better than wd-40...plus after soaking it overnight empty the oil out and with the glow plug out heat up the block with a heat gun before turning over, the heat will help to loosen up the gunk...

we had filled a zip lock bag with the marvel mystery oil and just put the motor in there. wierd thing is, it started to bubble a little. dunno what was happening, but the next day the motor was good to go once we cleaned it off.

the bubbling was just the oil going into the engine and the air coming out...
