hey, thanks, great info!

I haven't put the cowl on yet, but it will get plenty of air, as the cylinder sticks out the bottom.

I tore apart the carb, and it had *&*^% inside it..I thought I had cleaned it, but apparently I had not. It is definitely clean now...

Anyway, it ran good for a long time, but I believe I leaned it out too far and it got hot.

I am switching props and will run it tomorrow. I need to get a 18 X 8 somewhere, and maybe I'll try your bambula.

I'll let you know how it goes. Thanks for the starting points.
