You take off the glow head and install a diesel head. This has a piston in opposition to the moving piston. The position of the contra-piston is adjustable with the screw you see in the head, in the video.
You adjust the compression ratio until the diesel fuel ignites by compression alone. From there, as the engine warms up, you continue to fine tune the compression ratio until you get a steady run. Of course the needle valve works in the usual manner.
lol those things don't rev for shit.

will it work with a regular head i could take the shim out to give it more compression
swabbster3 2 years ago
Fixed compression can work. But the compression ratio required can change from day to day or not be optimum.
Colder weather can dramatically change the required setting. Even a slight loss of the very volatile ether in the fuel can make a big difference.
And taking out the shim won't raise the compression enough.
Go to Davis Diesel Development. They have heads for a hundred different engines. They also sell the fuel.

Hello
Allways fun to watch your videoes hopeso.
Congrats on the custom diesel head and the exaust rig. My exaust rig is a hose into a bucket of water.

Thanks,
I had considered that but was concerned about excessive backpressure. Maybe not an issue with the .40 but perhaps with the .06?
In any case, we have further developments, see the addendum.

guy uses propress

That refers to 39% ether, 39% kerosene,20% castor oil and 2% Amsoil, Cetane Booster.
This formula ensures easy starting and adjusting with good power.
Larger engines like a .40, for instance will tolerate less ether and more kerosene and still allow easy starting and handling.
My .40 formula is 20(ether)58(kero)20(oil) and 2% Amsoil.
Ether is expensive and big engines are thirsty so I reserve the high ether fuels to small engines.

what is the 39/39/20/2 fuel?
I mean what is it made out of in these doses?
