I have a Norvel 25 big mig engine. Runs great. I want to convert it to diesel, I have a drill press dremmel etc. but no lathe or cnc equipment. Are there any instructions on how to make a deisel mod for the norvels? If you can, plz post pix of your converted norvel and some instruction. I am very experienced with engines (glow, gas, co2, steam) but I don't own any deisel engines. I am comfortable risking possibly destroying my engine ($27 on ebay).

Your best bet is to contact David Diesel Development and see if they can machine up a diesel head for you. They may already have the specs for your engine and can whip one up right away. You basically only need a diesel head for your engine and you'll need to replace the fuel lines with diesel proof lines.

They are the center of the universe for modern diesel engines and conversions.
Unfortunately you would need a way to machine a new head with a contra piston in it. You cannot do that using a dremel. You would at least need a lathe to do it with. A milling machine would be a plus too.

thx

If it's Norvel and diesel, maybe I can help,,, if it's not too late.
