Well,

I took every thing apart. I did away with the fuel tubing in the center of the clunk line as mentioned above. I put a differernt clunk on there (the one from my old plane). I put new fuel line and then I tried it.

Rather that putting everything back all perfect I figured I'd take the smart approach. I left the foam padding out, left the receiver hanging. I singled nutted the engine mounting bolts because it takes me forever to double nut them. Basically just did what was necessary to try it just in case it didn't work it wouldn't be so much wasted work.

Well, it worked perfect! No air in the line, ran great. So, I spend an hour and a half buttoning everything up, adding foam, the whole 9 yards.

Then I tired it again. It still runs great, but at full throttle there is still air bubbles (before the needle valve) [:@]

But like I said, it runs good. A tad bit unsteady at full throttle. But I think I am going to go with it.

I have a great planes tank. The exhuast line is just a port straight into the tank. It doesn't have a place where you can install a fuel tube bent upward. I wonder if that could be the source of air?

There is really no since in taking it back apart because I just replaced everything besides the tank. My major problem was the split fuel line and that is fixed.

Is it out of the ordinary to see any kind of bubbles in the fuel line?

Thanks for your help guys,

Wings
