Les, I bet you are starting to like that engine!  For us, the slow rpm, compared to the half vw is strange to get used to.

For the bigger prop, did you have to shift the thrust line?  Lengthen the landing gear?

Thanks.  When you have accumulated some air time it would be great to hear about the flying characteristics compared to the 1/2 VW.  I love that radial, low RPM sound!

Update on progress so far:
Carb settings do not take much movement to make a difference. The LO side screw was easy to get set but still working on HI side screw. From what I can found out starting point is 2 turns out and it should not take more than 1/4 turn in or out from there. At 2 turns out the CHT is running about 300 and EGT at 800 at full power. At 1-7/8 turn out CHT is 350 and EGT is 900.  The CHT seems to respond to changes more than the EGT.  I have tried a total of 3 different locations for EGT and have moved both CHT and EGT to lower right cylinder, reads same as the top cylinder.  I still have some tuning to do but it is doing good. In level flight without at same altitude at WOT i am seeing 2,400 RPM.  Climb is consistently better than the 1/2 VW. When we get the starter and ring gear removed, once we figure out how to start the 3 cylinder radial by hand proping, we should be about 3 lbs. lighter than the 1/2 VW.
Vibration and sound at idle is good, there is a range between about 900 and 1300 the engine likes to shake. Above this range it again smooths out and does good.  Flying behind the radial brings new vibrations and sounds i need to get used to.  When the head set is removed in flight the engine sounds like it is just loafing along, more prop and wind noise than engine noise.
