I took the fuel tank off and checked the reed. It was clean and worked one way and not the other.

I tried to fly again on Sunday but the engine still didn't behave.

For the glow driver, I am using a remote start adapter plugged into one of the one (NiCd) cell drivers. I use a cotter pin on a short wire to attach to the glow plug. The glow is nice and orange and when there is fuel in the head, you can hear it sizzle.

I had another plug, and when I tried it, the engine fired up better but still wouldn't catch. Not sure how this is relevant but the two plugs I tried had different markings. One had lines coming out of the top surface and the other didn't. Are these lines significant ?

Sometimes when I had the starter on it, it would turn over and it sounded like there was no glow but I knew there was glow because the ampmeter was showing current flow.

It seems like the needle was very sensitive. It would run well for just a little bit and then die.

So, I had a baby bee engine and I moved the needle valve from it to the black widow. The engine seemed to run better but again it wouldn't run for long.

We tried Cool power 15% fuel and the engine didn't run any better.

The conclusion we were coming to was that the engine must have an air leak. Where should I look for what ?

How do you seal the tank to the back plate ? I was thinking of using some epoxy.
Where do you get backplate gaskets ? gaskets for the venturi ?

Thanks.
