Is the 219cc engine single-cylinder? If there were two, you could deactivate one. Could you take the 219cc engine and install shims and custom parts to reduce its displacement? Hopefully the diesel's efficiency would balance out all of that weight!
This is .2L, which is only 10% smaller: Tractor Engine (R165)>>

I was not familiar with the Avero Ultra-Lite. It looks pretty interesting. Have not been able to find much about it yet.
The 219cc is single cylinder. We are looking pretty hard at taking either a gas 125cc or a diesel 219cc and sleeving the engine to decrease the displacement. Our thought is that this would give us a beefier bottom end that could handle the diesel.
We are still trying to understand why a diesel engine needs to be beefier than a gas. Can someone help me understand this? If a 125cc gas engine can get a more power from a 125cc diesel engine why does the diesel need to be beefier? I guess we are not understanding why the diesel pounding is more damaging than a gas engine's pounding.
For the competition our engine must be 4 stroke and run and start on plain jane diesel.
elhigh you are correct in your statement.

Unless I misrecall the most competitive teams are now insulating their engines to keep the heat in, and do low speed pulse-and-glide to maximize matching their engine's loading to its best BSFC point.

We can warm the engine up before we run it in competition. During competition we only run the engine for short times so we are turning it on and off often.
