Glad to see you got it running good.We would love to see more video of your country.

Sorted, sticky valve, free'd off and push rod refitted. Rod not bent, looked good, runs great now.

The 20hp Kawi hates old fuel, and any water in the fuel. Both issues can cause the valves to get sticky.
Sounds like you got her figured

I am away to get stuck into it.

It's 9:30 am in Scotland so I'll let you know how I get on.

me thinks you are correct sir.likely have a push rod popped out from under the rocker.my valve train was all sticky and the rod kept popping out.

I got my carb problem sorted out, she is idling and revving ok, running on both cylinders.

When I put it into gear and try to move the machine only runs on the front cylinder.

I have changed plugs and run some ATF in my fuel.

Should I take off rocker cover and check for sticking valve?

Cheers Rory
