...Of course, there won't be too many occasions where a throttle slam is desirable over smooth motion of the throttle stick. On to my question>>

I bought a Brison 3.2 almost 2 years ago, and finally got it in the air yesterday. Hadn't ever run it before that. Hadn't run any gas airplane engine before that. However, the previous owner had run it for a few gallons. It ran perfectly, especially considering the time it spent static on the bench. BTW, it was kept in AC-air, oiled, and turned over every few weeks. Anyway, got it going, let it warm, ran it up - all without a problem. Didn't touch the screws. The only worry I had was whether the mixture was too lean. Pinching the fuel line doesn't seem to have an effect on the walbro carb, and I didn't see any visible exhaust. I'm used to seeing some oil smoke from pre-mix motors and didn't see any here. What do you think? Was I running lean? Didn't check with a tach because it had been jostled on and my new batts were dead.

The other concern I had was it's ability to prime itself. I have about 8" of fuel line and it didn't draw fuel down the line by itself. I pulled the line and tipped the plane to prime the line, then put it back on the carb. Choked with ign off, I didn't see any visible fuel movement in the line when I flipped it. It took about 12 flips on choke to get a pop, then another 10 to get it started. Could this be a result of sitting along time as well? Suggestions?

Thanks
