Check the onboard glow driver - does it work properly, is the battery fully charged before the first flight. I'd also replace the glowplug in that cylinder just in case - even if it checks OK. I'd recommend using OS #F 4-stroke glowplugs. Keep in mind that if the onboard glow works properly and one of the plugs cools during flight, you need to bring the throttle stick back to less than 1/3, so that the glow driver fully energizes the plugs. Do it while the plane still has enough altitude - it will take several seconds for the cold glow plug to warm up and burn the excess fuel accumulated in it.

The engine also has separate needle valves - improper adjustment to one of them might cause a flame out to that cylinder. Make sure that both cylinders run slightly rich on the ground.
