Look at your 2150 for me.....

I've had a drive/run issue at steady speed.
Well I've tracked 90% of it down.
Seems the variable high-speed bleed system cam was stretched/worn on the
throttle shaft. #3 below.

I managed to squeeze it together enough to make it lift the needles now.
#1 below.

I got a little pop/burble now just as I open feather the throttle.
There is no information I can find on-line about this part short of.

But it gives no specs.
So if one of you that did the 2150 upgrade and is running perfect or nearly so, better if a few did it for reference.
Look in your carb at #1 above between the Venturis and open the throttle (with engine off of course) and see when it starts to rise.
Does it move at the slightest crack of the throttle or does it start moving after ??? percentage?
