no, no damage. Its just going to load up a bunch in transition or when you hit the throttle hard. The way to set the low speed up is to keep turning it in, checking transition, and when you get to where it cuts off, back off just a little on the low speed mixture and thats the spot.

The dynamix carb is a bit different in design. A bit ahead of its time in some ways.

Some folks got frustrated with it because they expected it to just run out of the box and expected it to run like a tight-neck venturi carb. It was designed as a performance carb. It needs serious pressure to perform and for the engine to run well. It does not draw fuel on its own. Pipe pressure or a pump is required. Usually the webra or other aftermarket "mufflers" did not produce enough backpressure or fuel delivery pressure to allow it to work well.

One of my best running webra speed engines was given to me by someone (1980?) after the guy litterally ripped it off of his airplane. Two weeks later it was in a Curare. The guy was dumfounded
