good going lol atleast you know it runs :D any videos of it actually going?

[anoblenate]

got a few with a cell phone camera but the quality is terrible. can't hear anything and it's quite distorted. Wish I did, though. It was fun to run and sounded great.

That was after fire, and Radials are common for spewing oil everywhere.

Reminds me a little too much of some of the cars I've owned over the years.

Not a backfire, that's an after fire

Where do/did you go to A&P school?

I've had some temperamental radial engines when I was in A&P school. If they don't want to run, nothing you can do will make them start! But once you get them going, they "purr" like a Harley!

ooo a nice radial engine...

You should try hand propping that. (I totally guessed it was a spark problem before you said that about the mags). Wish I had a camera on some of those test run days when I was in A&P school :(

we actually had a few guys hand prop it once it was running well. the best was the smallest guy in our class doing it since this was the largest piston engine we had.
