Default New Problem

My Jett 50 is chewing up spark plugs like candy corn.

Its been about a month since my last flight on this plane, so today I took out my Patriot(55ax), H9-F22 (Jett 50) and took em for a spin or too. Fired up the Jett 50 on the bench it tached 15,300, thats about 600 less rpm's that the last time I flew it. Using Omega 15%, turning a 10x6 apc prop and using the Mccoy 59 plug. I took to the air 2 minutes into the flight the motor started sputtering, landed it just as the motor died. Glow plug was bad, put in a new plug (same type) and tried it again with the same results 2 minutes into flight motor sputters and I land. This time I was able to keep the motor running for a few seconds and I noticed a large amount of bubbles in the fuel line, then the motor died. Pulled the plug and it was dead as well.
What could cause the plugs to blow like this? I will pull the cowling and check for leaks in the fuel line..

Thanks
