I didn't see anything on the forum about it but the H4 shindaiwa Hybrid engine is an amazing engine. Yes you still have to mix oil but it idels so quiet and at full its much quieter than a regular 2 stroke. I think I might try an order one of these engines or find one used I know they make a 72cc for a blower. Best thing is though is it is the same weight and size as a 2 stroke engine.

That engine would be terrible, it combines the worst aspects of both 2 and 4 strokes. Using total loss lubrication, compressing the mixture twice and the unneeded complexity and weight of valves.
Don't buy that.

IDK if it gets mixed more it is the fumes that burn wouldn't that be better? I wonder if that's any part of the fishing reel company Diawa? Their name is Shidiawa.

msrfans 24" race bike build uses a similar motor.
I can't wait to see it run.

4MIX STihl. Dry sump pushrod motor with their unique oiling system. That's right, a four stroke that uses mixed fuel. Lots of torque and runs great. Headless top end, plastic one-lobe cam and adjustable rockers.
