I have a new Magnum 70 4s running a 12/6 master airscrew. The problem is that is does not seem to run as fast as it should. I have approx 5-6 tanks of fuel through it. I don't have a tach but it just doesn't peak out. Runs very rich in the air. any suggestions
GOIRISH. First off GO IRISH. I hope this is a better season than last year. Now as far as the Magnum Mine was doing the same until I put a tach on it. I had the high end way to rich. Get a tach it will help you out a ton. I went from 12k to 15 k . JMHO.
