4. Assemble the heater parts.
4.1 Apply RTV sealant to the end of the copper
breather tube, GM19464 (included in the kit), and
insert it into the drilled hole in the heater,
GM19463. See Figure 4. Press the breather tube
approximately 0.4 inches into the heater plate so
that the end of the breather tube is flush with the
inside diameter but does not extend into the large
opening of the heater.
4.2 Place the heater on the carburetor without a
gasket and adjust the angle of the breather tube to
line up with the breather nipple on the engine
crankcase. See Figure 5.
4.3 Install the breather insulation, GM19465, over the
copper breather tube. See Figure 6.
