Assembly - Tecumseh TC Series Technician's Handbook

17. Attach the ignition module, use the proper air gap
gauge between the flywheel magnets and the module
laminations (TC300 rotary mower applications and all
TC 200 models use air gap .0125" (.317 mm) part #
670291. All other TC 300 engine applications use a
030" (.762 mm) air gap or part # 670321). Torque the
module mounting screws to 30-40 inch pounds (3.3
Nm - 4.5 Nm). Remove the air gap gauge, rotate the
flywheel to assure it does not strike the ignition module.
Attach ignition grounding lead to the module terminal
(diag. 7-20).
NOTE: When using .030" (.762 mm) air gap gauge, it
is critical to push the module against the flywheel
magnet before tightening the mounting screw.
18. Install the blower housing and rewind assembly.
Replace the debris guard if applicable.
19. Connect the fuel line at the carburetor, position the
fuel line clamp on the fuel fitting, and attach the fuel
tank to the engine using the mounting spring. On TC
type II engines, hook the upper fuel tank mounting tab
over the blower housing stud and the carburetor studs.
Make sure the "O" ring is in position between the fuel
tank and the carburetor. Tighten the retaining nuts,
install filter(s), and attach the air cleaner cover.
20. Reset the governor and / or speed control using the
procedure in Chapter 4 under "Service".
21. Install the spark plug and connect the high tension
lead.
