Engine stalls after 2-3 minutes of flight
I have an evolution 45 engine on an Alpha 40. I have aprox 3 hours max on the engine. The first three months I have been flying it, the engine has run like a top. Then in Sept I started to have problems where it would quit after two or three minutes of flight.
I have worked with several experienced pilots at the field and we get it running very good on the bench and then once again in flight the engine quits. IA month ago I tired a new glow plug (#8) then in late Nov I switched to a #6 plug to allow for the colder temp around 5 degrees Celsius. All that to say I have had aprox. 15 flights and have had to dead stick all but one of them. Although I am getting very good at dead stick landings like you said earlier it gets old fast.
I need a reliable engine so I can fly with skiis on the snow. I am afraid that the bearings are already gone or the engine is already ruined. Thank you for any advise you can provide. Dan
