Remove the dizzy cap and the hose from the vacuum pot. Suck on the end of the
hose to induce a vacuum into the unit. If you can't
create a vacuum, the diaphragm is broken. If you can create a vacuum, watch
the distributor plate to see if it moves. If it does then
the unit is working. If it does not, disconnect the vacuum unit and see if the
plate is free to move. If not it probably can be freed
up using penetrating oil.
This is the "Shade Tree" method! No tools required!
