When good planes go bad.

I have an old Twister with K&B Sportster .28, It's usually rock solid but for some reason today it wouldn't run right to save it's life, every time I took off it would go lean and die, I've gone through everything, tank (Sullivan plastic) tubes, needle, plug, everything.   Very strange

Sounds like vibration. does it have the Fancher tripler on the nose?

            Possible air leak at the venturi?

[Pat Chewning]

My engine did that the other day.  The fix turned out to be to replace the gasket on the backplate.  My other engine suddenly developed the quit-in-the-air thing and that one was caused by crap in the fuel filter, fuel lines.

This is where I'm going to start, I have a feeling you could be right.

What about fuel. It has been very humid lately Dwayne and moisture in the fuel can cause the engine to quit. We had a case of that at Summer Stunt. Switched to a different fuel and motor ran perfect.

I went thru that one day when my son wanted to fly.  Engine would start, set needle and launch.  A lap or two and quit.  I changed plug, changed fuel, pressured checked tank and checked filter.  What I missed was a pin hole in the fuel line at the spray bar.  Replaced fuel line and all was back to normal.

Speaking of fuel, what are you using these days? For those that don't know the Morgen fuel distributor for  Canada ran into some trouble so it's no longer available in Canada, our LHS was able to get some Byron but now that's on back order, I'm about to burn the last of mine so until this is resolved it's E-stunt for me.

Can you get decent fuel in Buffalo, maybe a case or three at a time? I'd drive to Vancouver if that's what it took, maybe even Portland or Eugene. Steve
