I forgot to welcome you! Thorry.
Are there even small diesel engines out there under 50cc? I mean diesels rely on compression to fire up. They don't even use a spark plug. They use a simple glow plug. The compression alone is enough to detonate the fuel along with the heat generated from the glow plug.
A high performance gas or alcohol engine you'll find 10 to 1 or sometimes even 12 to 1 compression for like dragsters and such. Normal gas engine compression for passenger vehicles are around 6 or 7 to 1 give or take. The Happy Time two stroke is even less I believe.
A typical diesel engine you're looking into the 20 to 1 zone.
Dawg. That takes a STRONG pull.
My dad had a Chevy caprice diesel back in the 80's. That puppy needed TWO batteries to start. It needed that much power to get that crazy high compression engine to fire up. And those Chevy engines didn't last for they essentially took a gas 350 and added liners to get that compression.
So like I said,you're gonna need a starter or Popeye's arms.
But if you can get it to work,that may be perfect for your mountains.
