Well since nobody but Jody has said anything about the way the engine runs with the backplate,I will.
I Installed the engine in one of my GB Sukhois, that was a job and a half,but we got it and I ran it today for the first time.
It took about 6 flips to get it to fire on choke and it did run for maybe 15 secs, I then started it again another 2-3 flips then let it warm up so it would transition somewhat then started to turn the needles untill I got somewhere close.
Now all I have for a prop is a APC 18x6 W untill my order gets here, so made that do for now.
After a finer adjustment on the low end and leaned out the top ,the engine would idle at around 1700 steady, it would go lower but being new and not broke in yet it didn't like it, so 1680-1700 is where I let it run at for the low, the high was to much I got 8340 on a new engine that isn't broke in, so i'm sure it will do better once I get some time on it.
I won't run it again untill my props get here. I hope I didn't screw up by not ordering a 19 inch prop. Oh well If I need it, I need it and know where there at.*L*
Overall I was very impressed with the engine and they way it's running, the 2300 ST that was in the plane won't hold a candle to what this engine is putting out.
Should be alot of fun when the weather permits us to do some flying here.

I did make a Single bolt prop deal that worked out quite well. I'll make up another and show you guys what it is all about.
Anybody else have there engine going yet, lets hear about it.
