Hi there,

Very, very old thread, I know... but...

Well, I have to messed up of HP 61 F's. Very mistreated by a dork. Maybe there is chance for a 9th life.
Two wrecks could make a working one.

Is there a parts listing to find? PDF-format. So I can reconstruct some details.

The sleeve is Schnürle ported, but old style machined, like a diked piston and sleeve.
Piston ring has no stopper key to slot and can rotate freely. The type of porting makes no need for it.
The ring is even grooved, so works like duoble seal.

The combustion chamber is a hemi type.
Bearings are stock type, easy to find.

Main question, how is the head shim/seal constructed?
On a technical drawing found in the reviews at Sceptre Flight, it looks like there are two in place.
1 to seal the sleeve,
2 a spacer to lock the separate cooling element.

The sleeve has no collar, as more common today's engines show.

Hope to rive this tread, most knowledge slips away on old age sadly.

And get a new leash of life for it...

Thanks in advance,
RCP
