I have heard of various, easily resolved issues with the larger ST engines, some of which I'm considering for my G3250 that I just bought and installed in my Goldberg Extra 330 77".

I have run about 4-5 24oz. tanks through it, the first 3 of which were with standard Omega fuel, super rich, and the rest of the time was in the air with Omega ST fuel. I can't seem to get past the engine leaning out in the air. I start it out really rich on the ground, no where near its peak RPM, and then in the air it sags out, especially during high alpha and high G maneuvers. The fuel tank is up as high as it can go.

I know it is still breaking in, and it's going to lean out, most likely, as it does so. However, I would like to be able to fly with it in the meantime. I've thought about putting a VP-20 pump on it, since I have one readily available.

Please, no Super Tigre bashing here, okay? I like Super Tigre engines and have always found resolutions to any issues I've had, and they usually run just as well if not better than their competitors who charge an arm, leg, and first born for less HP!!!!

That being said, your suggestions and input are welcome. =)
