Got mine a week ago and after one liter of break in I think is ready to fly. Very good idle, good max rpm but very sensitive screw for mixture. Notice for first 5 min run take throttle full open and maximum mixture screw open to bring low head temp (about 40 degree celsius):

I will try to built a brass tuned pipe after few test flies.

I will buy another because I'm very satysfied

I've had an ASP40 water cooled, and everything fine except the carburettor. Pretty much everything that could go wrong with the carburettor did. If you stick to the stock muffler, you could be fine, but I was running a tuned pipe, and getting some pretty good revs out of mine, in a jet boat. Not sure whether they have changed carburettor, or if different sizes perform better, but keep an eye on the settings, I found they kept wandering.

discussion section not working.

if this is a watercooled marine engine, why is the reccomended prop size 8*6, and why is a plane muffler included?
