Tecumseh V-twin - Timing on a Solid State Module; Service Tips

6-4
Timing on a solid state module is not adjustable. The
proper air gap of .0125" (.3175 mm) using Tecumseh
part 670297 and the correct flywheel key in good
condition are the only timing variables. Set the gap by
placing the gauge between the flywheel magnets and
the laminations of the module. Tighten the mounting
screws to 45-In. lbs. (5 Nm). Remove the air gap gauge
and rotate the flywheel slowly by hand to check for any
possible striking points. (Illust. 6-6)

• Use flywheel fans with cooling fins that are damaged
or broken off.

solid state module.
• Store a solid state module within 20 feet (6.1 meters)
of an unshielded welder.
