strange clicking sound

[cooldude879012]

well I've got my tank and carb prob sorted out but now I've found a new problem when the piston reaches tdc there is a strange click it only happens when it reaches tdc and only does it when its being spun the correct way i also have roto start on this engine and i am hoping it that thats clicking but if not id like to know if this is a serious problem.

I heard that too in mine, it went away after i took off the backplate to cean my owb, if you do try takin of the bacjplate make sure your piston is at tdc otherwise it can get damaged.

let me know if it worked out, i have a feeling it had something to do with the roto start assembly.

problem wasn't the roto assembly, the piston was just barely tapping the glow plug, I'm lucky i caught it before running it. i think ill put in a shorter plug or put another spacer in the head.
