Hi,

Just an update.

After I drilled out the carb input, I ran it today in the back yard first with the baffle left in - it worked great except it would tend to lose power with the nose pointed up.

I removed the baffle ran the engine again, had to readjust the high speed settings, but the engine ran very well.

It looks like tomorrow will have a cloudy, rainy day with some sunny periods. If I can, I'll test it at the field tomorrow, only "real" flying will tell us how it works.

I suspect the problem was fuel starvation at high throttle.
