Hi -
The engine is not new, but it's in like new condition. The needle valve has been closed and open so I have no idea what to do to this engine to start it up.

I turned the prop a few times and gas went in the carb. so I tried running it and it ran for about a 2 seconds...

what do I tune the needle to at least run the engine to tune it?

also, what would be the ideal prop for this engine?

Does anyone have experience with SK 80 engine? please share. thanks
