Well done Ed. By my calculations of effective choke area, your engine needs to turn minimum 8,400 RPM for decent fuel draw. Can get away with slightly lower speed when run on the bench as you have arranged, with minimum "lift" needed. Getting that right is oh so important, as gravity feed is...

Ethylene glycol is corrosive. Coolants containing it have additives to protect engine parts. These degrade with exposure to air but provide adequate protection in a closed cooling system, for the recommended service interval. Not suitable for vintage cars with cooling systems open to atmosphere...

Would this ignition system work on a regular old-time model airplane engine with regular contact breaker points and running at up to 10000 RPM?

To me this indicates either poor crankcase sealing or maybe poor venturi effect. I did seal the head screws into the case but maybe I need to check the rear cover and perhaps the cylinder to case sealing. Having said that, the impromptu carb throat is probably too large but the one I made is...

Regarding the Nano .1cc diesel starting, you're not alone. I've struggled with AE .1cc, the .1cc Valentine DIVA and one D-C BAmbi. Although another Bambi was fine. I don't have the complete answer, but did find that reducing effective choke area helped with starting. From memory, the Nano has...

Hi Gang, I built a small diesel engine that has a 3mm pressed-in crankpin. Didn't get the fit right and it came loose. No big deal - just make another hole in crankweb and try again. How much smaller should that hole be than the actual pin size? For folk who think in inches, think about fit for...
