B. Removing Debris from Engine

Before each use, remove the air cleaner cover. Remove grass clippings, dirt and debris from the following areas:

Levers and Linkage

Cooling Fins

Air Intake Screen

Air Inlet

Guards

Removing debris will insure adequate cooling, correct engine speed and reduce the risk of fire. See Figure 32.

C. Spark Plug

Check spark plug yearly or every 100 operating hours.

1.Clean area around spark plug.

2.Remove and inspect spark plug.

3.Replace spark plug if porcelain is cracked or if electrodes are:

Pitted

Burned

Fouled with Deposits

4.Check electrode gap with wire feeler gauge and set gap to—.030 (0.76 mm) if necessary. See Figure 33.

5.Install spark plug and tighten securely.

NOTE

A resistor spark plug must be used for replacement. Contact your Authorized TecumsehPower Servicing Dealer for a genuine replacement Resistor Spark Plug.
