Just took delivery on a new Vess 22A for the DL. That prop is a thing a beauty. Almost seems a shame to drill holes in it. Hope it helps bring up the revs to what others are getting. I can't seem to get past 6400, but I am still on Lawnboy at 32:1 and 22x8 Master Airscrew. Perfomance and reliabilty though have been great. I'll post some rpm number after this weekend as I plan to switch to sythetic oil.

Hope you get you engine sorted out, Paul.
