Hey capt :-)
I have read the pages and now I'm back
with another silly question have ran my engine for the
first time it ran started fine and after a few minutes tweeking
the high and the low end and started again I notice
some black exhaust all under my plane is that normal.
I had a hard time restarting and gave up will try again
when my shoulder muscle recovers

I want to thank u in advance to everyone that has
replied to my problems thanks
