I've never owned a 49cc HT engine. Are the jug studs the same length as the 67cc? How long are they?

My manual shows the jug screws to be 6mm x 112mm. I asked the question in another post," where to buy studs" thread. I would think the threads are bigger, like 8mm. I do not want to untorq heads and then try to find parts.

Thanks!

Looks like pretty much all head studs I've checked are 4.4-4.5" long regardless of displacement.

Three thread sizes have been used as far as I know. M6X1.0, M8X1.0 and M8X1.25
