Just been mighty busy @ the store. :msp_w00t:
I did run it some more on Sunday morning.
Took it home and plugged it in to the diagnostic tool. Learned all kinds of things. I've started it 16 times and I have 29 minutes of run time on it. The maximum carb temp was 114F. How many seconds at full throttle, and at idle. Pretty cool. Don't know that it's all that useful, but it's pretty cool.
Power still seems equal to a stock 346, although I didn't have one with me Sunday. Still need to play with these things before drawing too many conclusions. Vibes, weight and handling are as good as it gets. I think there'll be some more power as it breaks in, but I don't think it will be an "Oh wow!" thing where it blows away the 346.
