I hope you are not going to run the engine without a prop, chance of runaway rpm that way. Get a "prop-tach" tachometer that senses light pulses from the prop. May be able to borrow one, they aren't very expensive, and then you can check the prop rpm.

Kevin,
Nice Rig, you will get it sorted, especially with
Ken helping you.

not as exciting as a first flight, but a
milestone for me. engine will only speed up to what shows as 1500
rpm. from the video however, I don't think that the prop looks like
500rpm to me, so I question if my tach is reading correctly.
beyond the alleged "1500 rpm" the engine dies unless I pull the throttle
back a bit [which is open all of 15-20°] much more to test and
learn. I will pull the prop so I can safely put a timing light to the
flexplate where I have timing marks. supposedly at 22°BTDC.
