Thread: The Wyvern Engine
29/04/2012 13:38:43

Hi Fred

I used the term micro for want of a better description.

Any small gas-valve, with multiple turns, between "off" and "on" will do. My valve has 16 turns - those used in small oxy-acetylene sets, would probably be suitable. but any, say, from an ordinary blow-lamp, would be too rough.

Regards

Hi Moose

The sizes, I gave were from the drawings of Wyvern. It occurs to me, that when Westbury designed the engine, gas meant, town or coal-gas; so the drill size may not be suitable for butane.

Wyvern was the first I I/C engine, I built, 30 odd years ago, but I cannot recall what drill size I used.

For your info, all of my 17 engines, run on butane. All need only, a whiff of gas. I use a micro-valve in the line. Starting problems are invariably linked to, too much gas, rather than too little. However, this should be no problem, if you are using petrol.

Hi Moose

The drill sizes for the fuel-inlet are no 70 drill for petrol and no. 50 for gas. The fuel-valve is the normal 45 degrees.

Hi Diane
 
I submitted a short article on mods to a small milling machine for MEW, which was accepted, but not published. It may have been early 2010, I think. About the same time, I sent details of i/c engine, Rina, published in ME, starting vol 204, No 4372.
