My JBA .56 is acting up again. Last time I used it (in January 2017, 50F) it ran fine. Today, with the temperature above 70F, I ran into trouble. Many times it would just die during the takeoff roll, and several times it dead sticked in the air. In all cases the feeling is that the engine is getting lean. Note that the problems I had in the past year the engine never actually quit.
Putting a new Enya #3 worked for one flight, then it was back to quitting. I took the head off and noticed that there is hardly any pinch at the top. Could that be the problem? and if so, where can I get a new piston/sleeve set? I could also try to remove the copper gasket and see if the increased compression helps... This time, the problems appear in normal attitude, e.g. during the takeoff roll.
