Laurence Mark Posted September 14, 2017 Share Posted September 14, 2017 My new paramotor, Skymax Expedition with Moster plus is sucking air into the fuel line when running. The bubbles in the fuel line only appear above the fuel pump bulb. A new one is being sent out for me to fit as a replacment. I am pretty new to this paramotoring stuff, two stroke engines, fuel systems etc. I first noticed the problem when it would only idle briefly then cut out just when ready to. Have others experienced such an issue in their fuel system? Quote Link to comment Share on other sites More sharing options...
Buyarbi Posted December 25, 2020 Share Posted December 25, 2020 Yes mine does the same thing. I have now heard of a few of these with the same problem. Mine builds enough air in the line to stall the engine at full throttle. Have no solution yet. This is a new primer bulb. Quote Link to comment Share on other sites More sharing options...
