Thanks, Don.  I run the drill bit at the highest speed my drillpress will go which is probably around 3,000 RPM.  I do also go slow.  The only place there's any burrs is on the inside of the steel valve tube.  I just ran the 1/8" bit back up there to clean them out.  I didn't have any problem removing the valve tube after drilling the radial holes in it.  I did mount it in my lathe and smooth it down some with 600 grit wet or dry sand paper but that was it.

I still have some work to do on it.  I'm using a borrowed flywheel for now and plan to make propeller out of steel as a permanent addition.  I also need to make a stand for it and mess with the timing some.  I've got the timing set backward so the engine is running in reverse, but that's easy enough to remedy.

Here's the video...  Couldn't be more pleased with the way it runs.  Do wish it was a little louder on the exhaust note.

Surprised it wouldn't run with the smaller flywheel.  I like the look of the one you made.

Sounds Great Chuck!   Love the sound!    I think it sounds like a Jenny....so a 4 blade old time prop sounds great!

Any possibility you could open up the exhaust ports a little?  That might make it louder.

Hi Chuck

First thing I have been doing every day is to check to see if you have the engine running.

Today was the day.   :whoohoo:

Congratulation on a great build, looks and sounds great.  :NotWorthy:
