hi mate im sorry i have just relized that my tamiya tnx 5.2r pistons do move up and down
i realized this as i have opened the engine but it is abit hard for the piston to move
so now do you have a solution to the problem as the piston does move?
please reply asap
Does the piston move when you turn it with the rotostart? If no, it's most likely the one way bearing in the starter case(on the engine). If yes, then the problem is not the starting system. Is it any harder for the engine to turn now than before(when it ran)?
