No port work yet. Just mocking it up tonight. 3mm spacer with two gaskets gets me to .018



Thin ring piston.



Assembled. Riser polishing is sure to shave a tenth off the times :rolleyes:

You could explain what yer building so us cats wit the plastic helmets can keep up. Geeezzzz.....

Funny, always pictured you as the tin foil cap type a guy :yup:

Well, this is a 350 with the epa 52cc cylinder(my personal favorite). Slug is a thin ring Mac Titan 50. The pin height is 3mm taller so a buddy machined a riser for me. The plan is to stick with the original intake and carb but we'll see how it runs.

The piston has 29.8mm between the pins so they will be set on the ex side. Trans will be wrapped way back.

52mm huh? What jug is that?



I do like a good fitting tin hat though. :)

52cc jeesh. 45mm I believe.

Have a pile of these so I'm gonna try a couple new things. Fingered one already but can't decide if its worth bolting it on.
