I'm on my second gallon; still feeling my way around the engine.

Top end is great, and way too much for the airplane. Best sequence speed is about 1/3 throttle. Unfortunately, I've got a pretty wide "rich zone" from just above idle to just under half stick where the engine is burbling and in general very unhappy.

Tobe said that was classic signs of a rich low-end; but when he leaned it, we lost the smooth transition it had. We tried several different needle settings, and then I had to leave. Of course, he's out of the picture now for the next six weeks...

I called Keith, thinking perhaps it was the white gas. Given how strong it runs wide open, he said it wasn't the fuel. He told me to check the carb insulator and a few other things. He offered to check it out, but I'll wait a while before pulling the engine and sending it to him. Its probably just my inexperience. It IS, however, somewhat cold-natured and finicky to start.

Basically, I think once I get some more fuel through it, I'll be okay. This is my first gasser, so I'm still learning about them.

But yeah; I like the concept. Gobs of power, practically no mess to clean up, and most important is the reliability. Even with screwed-up mixtures, it still runs.
