I pinched off all vacuum lines to the mixer and intake manifold.
Attached a vacuum gauge to the fuel intake port on this CA110 and I get absolutely no vacuum on the gauge when cranking no matter what position the accelerator pedal is in.
Now this unit will start and run and idle great when I crank and prime it by pushing the primer button on the Model J. It just wont start on it's own without priming.
Seems to me the diaphragm on the top of the mixer is not raising enough to let any fuel flow down the center of the mixer.
This is weird I have never had this much trouble with a mixer before, but usually I'm dealing with a CA100 or CA50 like most older units had.
