Hi

I have had some problems with my leo.
It has been standing still for 4 months due to not being able to start.

The symptoms are as following.
It got a spark, it gets gas and i have cleaned the carburator to make sure that it works.

Now

The leo can start and can only run with VERY low rpm. ( the wheel is not spinning)
And when i try to give some gas, it dies - very quick.

I have checked the valves and cleaned them, tjecked the valve-timing.
Changed the ignition coil and the coils at the rotor.
The compression is 9,5bar.
And when the engine has idled for 5-10 seconds, the sparkplug is BLACK and it cannot start anymore.

Then i change the plug and it can idle for 5-10 seconds again and then i dies.

Do you have any suggestions? i am desperate.

You can reply in german, i understand it.

You can see this youtube video from yesterday, when the caburator could take a littlebit gas.

possibly your choke piston sticks, or the carburetor gasoline level valve sticks ?- both resulting in very rich mixture
good luck for the search
