DO NOT USE TRACKER DIAPHRAMS
FOR REGULATORS...
They WILL LEAK...
Despite what you see on "forums"...use of Tracker Diaphrams on Regulator Assemblies DOES NOT Work. Tracker Diaphrams ARE NOT SAME SIZE as Regulator Diaphrams from a used engine.
Regulator Diaphrams ARE DIFFERENT SIZES as well. Air and Fuel Regulator Diaphrams ARE NOT SAME SIZE. A Fuel Regulator Diaphram WILL LEAK in the Air Regulator Housing.
Spring Tension MUST BE SET for proper pressure.
