rstearman, thanks for responding, the engine has no more data already started, it says at the bottom of the cylinders R028131 150 a1, where should I look cylinder numbers that you say?

Usually on the base of the cylinder.
Here's an image of a 3.2. 44ZN 16 W 3 Mahle exhaust mounting holes are parallel
Check your muffler mount hole location

I found a thread here on RCU that may give more info, I met Tony a long time ago at Fresno jets.
Buena suerte con la maquina.

At one time Airhobbies was located here in NC .I remember seeing them at flyins around the state and at Joe Nall. They had a great idea with the muffler mount but the engines were tight and lacked performance. A few friends had the 3.0 twins and were not very happy with them because of the weight and low power , they rarely hand started easily .
Best of luck on yours

Not too expensive to replace ign with new type with shielded spark plug leads and caps.

The plans put cdi, we do a test on a bench as well as this original just to see how it works lol. Now I'm repairing carburetors and since then I'll put up.
What still nobody could tell me is how many cubic centimeters is the engine, I'm not sure propeler use. Thanks

I dont know what the actual HP is but I am sure that it will be a weak engine compared to any other of the same size.
Put a prop on it and bench test it. I wouls start with a 22x10 prop and work your way up from there if possible. I suspect you will need to put kits in those carbs and I would also replace the Ignition with an Rcexl or CH for reliability.

Already started the engine with a propeller 22x10 seems little power for a 80cc, but regulates and accelerates even I will keep trying with other helices and definitely will put cdi to see if it improves and is more reliable
