Longboy,
I must admit this engine is a mite unconventional, but it looks good and has some great ideas.

Hi Dave, a very nice engine. I do like the open style, so a lot of motion is visible for the observer.

Runs great, starts with the flip of the wrist. Nothing to complain about there.

Thanks Crueby.
What I find in building I/C is that when troubleshooting, when everything is just right they will hand start easily and stay running. Using the drill to start  and the engine runs and stalls/ struggles.......it's telling  you, "not yet, I need more work". Is it fuel mix, valve or spark timing or a tight spot in the reciprocating or rotating assembly? This is a hobby of patiences for sure. :wallbang:   Dave

Thanks Zeepro...
Using these  model airplane .10-.15  carburetors on my engines, I set for a constant run around 1000-1200RPM idle. They stall out for me when I open the throttle at just a few hundred RPM above idle. I believe this to be the sudden fuel lean out and fixed, no advance ignition timing. Maybe using a R/C buggy carb as their engines respond to on /off throttle input would help......but I would be still short electronic ign advance. Mechanically, they should go a few thousand RPM but being free standing designs, my motors will walk around on the table then!  Happy that they idle smoothly till they run out of fuel.   Dave.
