ADJUSTMENTS
Suggestions: Check all connections for leaks and lines for bends or dents that will obstruct the flow.
A leaky vacuum tank float allows gasoline to pass into intake manifold through suction pipe, causing engine
to "gallop" on account of rich mixture. A leaky flapper valve destroys the vacuum and prevents fuel being
drawn from supply tank. Be sure all pipes and connections are free from leaks.
