Carburetor and Spacers
Your engine may be equipped with either a cyclonic air
cleaner assembly or a low-profile air cleaner assembly.
On engines equipped with a low-profile air cleaner, the air
cleaner base makes use of 4 studs that secure the intake
adaptor, carburetor, spacers and gaskets to the intake
manifold.For this style of air cleaner, proceed to Low Profile
Air Cleaner Equipped Engines, see Figure 76.
Engines equipped with a cyclonic air cleaner assembly will
have an intake elbow thatmakes use of 4 studs to secure the
carburetor, spacers and gaskets to the intake manifold.For
this style of air cleaner, proceed to Cyclonic Air Cleaner
Equipped Engines,see Figure 75.
