I got a buddies rc10 .15 ... it will not start for anything , stripped the motor down and cleaned it all out cause he said it sat for a year , with FUEL in it
. well when i did this i come to fine metal fragments pressed into the motor casing where the piston arm lopes, not sure of this but is there supposed to be a piston ring in the groove on the piston itself cause if so then i think the metal fragments are the ring. any comments are appreciated .
p.s it also dont build up enough pressure in the exhuast to push fuel up like its not getting compression this also leads me to the ring
