How to use plastigauge for measuring head clearance

That's a Nelson engine

No it is DKT, Italian engine and a Jett crankcase in the background. All pretty similar but Nelson is the best.

I make these for the RC pylon race community, it bolts on in place of the head and you get a reading and then do the same on the head, these come in a nice wooden box with the allan wrenches, I could do some for the marine engines, or alternatively do some glow plug mounted types.

In RC pylon they fool around with the deck height quite a bit (cylinder shims) to raise the exhaust timing, that is why the flange type is used there.

Hi Barry, i would definitly be interested in a glow plug mounted type (standard plug and turbo).

OK let me work something out.

Thanks. Was also looking in to the speedmaster adapters, but would like a digital gauge. So if you can built a digital one that would be my preference.
