how to run engine on engine stand

it can be run without the pipe on idle. but not well or very safe

did you make a stand for it? or you will have one helluva time holding it still haha
 
Just who is going to stop at idle when an engine springs into life.

The temptation of giving it that little bit of throttle is overpowering and often wins.

Never, ever start a modern day 2 stroke without a pipe, it will run lean.
