If engine misses when load is suddenly increased, remove pump
jet and clean with compressed air. However, it is usually advisable to replace
the pump jet, as its cost is nominal. (All jets must be seated gasoline tight.)
This condition may also be due to damaged or worn plunger leather in accelerating
pump cylinder or discharge check in discharge passage. If plunger is removed
from cylinder, use care when installing to avoid damage to plunger leather.
Correct air fuel ratio is provided by a "balance tube" in the air
horn. The balance tube should be checked each time the carbureter is serviced
to see that the passage is open. Theobject of a balanced carbureter is to provide
a constant air fuel ratio regardless of type, size or condition of air cleaner.
Should the cleaner become clogged, the capacity will be reduced but the air-fuel
mixture ratio will not be changed.
A fuel filter is incorporated in the carbureter bowl casting. It should be
cleaned periodically by removing the filter bowl and element (small discs).
Soak element in acetone or a mixture of half and half Ethyl Alcohol and Benzol
until all foreign material dissolves. Then allow to dry. CAUTION—do not
blow off with compressed air which may damage discs.
