It's fascinating to learn the details of an engine I will probably never have the pleasure of seeing in person. Thank you.

Thank you sir! I like all kinds of engines and I intend on installing different engines on my karts and playing around with them. I am glad you also have a interest! :thumbsup:

These are really cool engines...

When you start it... Does it turn over easilly before it starts... Or do you feel the compression on each cycle/rotation???

I'm trying compare it to like a clone with a compression release, or like those small pull start diesels.

These engines pull over quite easily due to the fact that the rotor is turning 1/3 of what the mainshaft turns so it would be kind of like pulling a single cylinder two stroke engine over at a slow rate. Many times people have been fooled into thinking that their rotary engine is worn out because of this when indeed it is not because of this. These engines start very easily as one can see in the video. These engines are a novelty in some aspects but I love how sooth running they are. You would have to drive a kart with one of these engines on it in order to see what I mean. Smooth with no vibrations.
Also these engines have a power stroke every 360 degrees but they are a four cycle engine. All of the cycles are 270 degrees.
Thank you for the question!

whenever I see/hear that engine.. I sooooo want one :(
I have no use for it, I have no space to store it in order to find a use for it,
I don't have the funds to buy one (they are expensive around here for some reason)...
my wife would likely drop it on my foot just to not yell at me for buying one...
but I really want one just BECAUSE :(

So yeah, thanks for that Bret :D
(no, honestly... thank you!)

Do those engines have a powerband like a 2 stroke? Or do they still make useable power at low rpms. I was also curious what rpm that clutch engages at since these engines rev higher than an industrial 4 stroke.

I discovered these engines a while ago and I have never seen one in person but I think they are amazing. Someday I would like to have one, whether it is just the engine, or possibly I could find one in an old snowmobile or motorcycle. I appreciate the videos a lot.

These engines have to a degree a powerband like a two stroke but different if that makes sense. The powerband is more useful in more ways than a two stroke. I have the gearing on this kart at 6.66:1 so it pulls really good from the lower rpm range and keeps on screaming to it's upper rpm level. I actually like this engines powerband compared to my two stroke engines and like I have stated before they are really smooth and are without vibration. These engines have had some bad raps from people but I guarantee that if they had one they would fall in love with them as I have. They do indeed like to drink fuel but that is not an issue for me. Not the norm for sure and I get a lot of people asking me questions about the engine and some of them don't even know how they work let alone know that they are the only engine besides the reciprocating piston engine that have been mass produced and used in a variety of fields.
Thank you for the interest :thumbsup: Oh, the clutch engages at 2500 rpm.
