Engine stalls while braking after a hot soak period may be caused by an overly rich idle air/fuel mixture due to internal fuel bowl vapors. To correct this,
install a new design vacuum tree fitting and hose, using the procedure below.
1.
Remove air cleaner assembly.
2.
Remove dashpot mounting bracket from carburetor (two mounting screws on the carburetor mounting flange facing toward the instrument panel).
3.
Remove the crankcase vent hose assembly from the air cleaner connector to the intake manifold vacuum tree.
4.
Remove remaining vacuum hoses from the intake manifold vacuum tree.
5.
Using diagonal cutters, snip off 1/4 inch diameter vacuum port from intake manifold vacuum tree to allow removal of fitting without interference
with coolant bypass hose.
6.
Install replacement intake manifold vacuum tree.
