I bought a used OS 25FP and today have magaed to get it running.
I started it quite easily but never managed to get a great deal of
power out of it no matter where I set the mixture valve.
There are two other screws on the engine, and I was wondering if
anybody has any default settings for all of the screws so at least I
can get it running and then just adjust the mixture.
Any help appreciated as it's starting to get cold up here in Canada
and the flying days are getting short.
