7. Mark the hole that the throttle linkage is inserted into
with a paint pen or marker. See Figure 3.6.
8. Remove the two mounting nuts and bolts that hold
the carburetor to the intake manifold. See Figure 3.6.
9. Disconnect the choke rod.
10. Disconnect the throttle linkage.
11. Disconnect the fuel line.
12. Drain the fuel into an approved container.
13. Remove the fuel line from the fuel tank and discard it.
NOTE: MTD uses low permeation fuel lines to meet EPA
guidelines. Low permeation fuel lines are made
with a soft membrane that lines the inside of the
line. Any tear in this membrane will allow the fuel
to get in between the membrane and the hose,
choking off the fuel flow.
NOTE: Every time the fuel line is pulled off of a brass nip-
ple, the fuel line must be replaced with the same
type of low permeation fuel line.
14. Install the carburetor by following the previous steps
in reverse order.
NOTE: The carburetors are not inter-changeable from one
engine model to another. To help prevent carbure-
tor mix-ups, the calibration number is stamped on
the carburetor by the fuel nipple. The calibration
code will be similar to or the same as the engine
model number.
NOTE: The slot in the governor spring bracket must fit
over the rib on the inboard carburetor mounting
flange. See Figure 3.7.
NOTE: Tighten the carburetor mounting nuts to a torque of
80 - 106 in lbs (9 - 12 Nm).
15. Test run the engine before returning to service.
