RE: Half A flyers! Look what I found! A true and valuable treasure!

Man that's great, my Dad has the book and I've always regretted not buying one while it was available. The Wellesley is of particular interest, I scaled it up to .35 size years ago but never built...

RE: Does head contour make any difference?

But injected diesels will indeed run rich though its not the problem it used to be. A rich diesel will emit white smoke which in fact is unburned fuel vapor.

In true diesels the combustion chamber shape is produced by a "re-entrant bowl" in the crown of the piston. In a true diesel fuel is injected into the cylinder at a predetermined time and...

RE: Rib-it!

Graham,

The "short eared" case was one with voids in the stack areas, chills that didn't fill them out. The rest of the case is sound so I'm going to build an ugly duckling with it.

RE: End of Contra piston diesels and glo engines?

The mini 4 strokes by Honda, which is probably what both of those mentioned here are, have a very elaborate lube system to allow it to run in all attitudes. It does not have an oil pump per se, it...

RE: Latest Restoration

Thanks George,

RE: What was AYSC?

I think it was the Nats. I was never involved in the program though I'm of the right era. The AYSC paid all expenses for the kids that qualified. I really don't know any more about it that that.
