[AT] LPG problems

[H. L. Staples]

Wayne the converter (guess it gets its name from the fact that it converts
liquid LP to a gas using the heat exchanger) is also the regulator.  

The vent is a small round opening on the front of the regulator some times
it is threaded, and is on the atmospheric side of the large control
diaphragm. If the vent should be plugged engine vacuum would have trouble
pulling the control diaphragm allowing more gas to flow. 

When the choke butterfly is closed more vacuum is on the control diaphragm
to allow a richer mix for starting. 

Rebuild kits come with a gauge for setting the internal regulating lever,
similar to setting the float level in a gasoline carburetor. 

Gotta go make some beds for onions and potatoes.

H.L. What are you calling the "converter"?  I have no vents (unless you
mean a line to the regulator from the air cleaner side of the carb?) on
the filter or regulator. I am getting plenty of fuel/pressure from the
filter into the regulator but  very little out. I can artificially
createa small increased fuel flow by creating a vacuum at one of the
regulator ports, but not much of an increase.
