ParCan:
I now have the Drawings from Stew. Thank you :)

I have been looking at the Cylinder and valve.

Forgive me, but where does the exhaust go ?

ParCan:
ok - ok I see.
2 X 4mm holes shown 20mm apart under the valve chest.

:doh:

NickG:
I asked Stew the same question a couple of months ago! Don't know how I missed it.

I do have another question for Stew though - how do you go about setting the valve timing when you cant see the valve and ports? Measure depth to back valve face through hole?

I did it by looking through the single inlet port, when the crank at the 12:00 oclock position you adjust the eccentric so the valve is not quite covering half the hole. second drawing from the top of the valve events on attached drawing shows this.

Hope this helps

Stew

NickG:
Thanks Stew, way off yet but good to know.
