Definitely different. Not as slick as Tower. But a well written email to Hobby People's Customer Service revealed my order for two was shipped. Credit Card site shows payment so all is well. Looking forward to test running one of these. Looks like they provide a pretty fair manual that can be downloaded. I like how I can decide if I want the needle up by the carburetor or hanging off the back crankcase cover. I'm old school and prefer the needle at the carburetor. But it's neat how they designed it so that you can have it the way you like.
