coast of Maine | There are two different "regulators" if you want to call them that.Possibly the final one ,just before intake,can get a tear in the diaphragm .It may idle fine but as vacuum increases from intake as you open throttle the diaphragm should pull back on sort of a needle in a seat.This or possibly a vacuum leak around intake or a vacuum leak to the very first regulator,(just a rubber hose from lower on intake),this one controls almost all gas flow for safety.Of course there are various systems ,,this is one I have. | |
