Microcosm / Okmomodel M15 and M26 engines first runs
« on: August 29, 2025, 12:57:40 pm »
Bonjour,

These two engines are quite similar.

My friend Eric and I have spent hours to find the correct adjustment of the needle valve combined to the accelerator but finally, we succeed !!!

Our engines are powered by 98 unleaded gasoline enriched with 4% 2-stroke oil.

My M15 is fully stock :

Eric's M26 is customized to be installed in a boat with a Microcosm / Okmomodel variable pitch propeller as you can see in the video :

G'day Raphael, glad you and your mate have them running well.
I hate using unleaded petrol for my H&M models, I just can't stand having the smell of petrol on my hands (and inevitably my clothes) and have gone full time to using naptha (white gas).
