I've noticed that on my Pegasus 240 engine cylinder No 3 (front right viewing from the back)
is always running very rich on idle and without the on board glow driver it would not ignite I tried to remove the igniter connector on idle and it died imediatly . I've checked the valves for correct clearance and I've found them to be O.K I also thought that the mixture needle was on the rich side but even leaning it ,it still was running rich. I have to say that the preoblem is until 1/3 throtle after that it's running okay but if I would not be using an on board glow driver that cylinder would stay dead!
