Thanks for the great advice, everyone. I have one last question that I just thought about...

Normally when I am getting ready to fly, I adjust the high end needle valve. The way I know I've leaned it out properly is to pinch the tubing that goes into the carb and listen for the engine to speed up. How do I accomplish this if all the fuel tubing is underneath the cowl?

I'm thinking I may have to run a little bit outside the cowl just so I can pinch it.

Thanks,
Patrick
