Hi guys
My Ign hit here today so I had a chance to run the 160, after a good warm up and some initial needle tweeking the engine would maintain a steady 1700 idle RPM with a high of 8850 -8900.
My set up was this
20-1 penzoil aircooled
88 octane pump gas
18x6 wide blade APC prop
Timing set at 28 Degrees BTDC.
Jtec exhaust diverter, not a muffler actually and made for a 108 to boot.
Elev. 4500 ASL
(Sorry no density altitude I forgot to call) But it was trying to rain*L*
New Bearings
New Bowman ring.
The engine before took a little to wind a 18x6 wide up, now its almost instant acts like a wood prop, the thing I really noticed is the smoothness of the engine, it seems as smooth as it was on glow fuel.
After some more run time and minor needle tweeking to get it dead on I really think I will enjoy this engine.
The low tick over at an idle is something to behold, I let it idle for a few mins while I walked outside and when I came back and nailed it, it was top RPM's instanally, no sag or flooded condition.
The low end needle is a little bit on the sensitive side but should be ok, the high adjust like a typical gas engine.
I did notice something, the ring looking thru the exhaust port is completly shiny now, I did get a little of the black splatters out of the exhaust which is normal, but the ring seated in very fast.
Compression feels good and it was one flip starts with no sign of a kickback.
All I can say is so far is that I am very pleased with the conversion and the amount of gas it used was considerablly less than glow fuel.
I have a xoar 18x8 laminated prop I may throw on it just to see what that will do, maybe to much we'll just have to try it and see. I have used a 16x10 APC pattern prop on it in the past with very good results, but I don't feel I will be able to run those props now again we'll just have to see.

Bob I can now understand what you have been saying all along, all I can say is what a little sweetheart of an engine with this set up.
