TEST OR INSPECTION
ENGINE FAILS TO START.
Remove air cleaner cup on models 2A016-1, -2, or remove air cleaner element Model 2A016-3, -4.
If engine starts, service air cleaner (par. 4-20).
Check ignition switch models 2A016-2, -3, -4 for continuity (para 4-17).
Replace ignition switch if defective (para 4-17).
Inspect spark plugs/High tention cable.
Clean regap or replace spark plug as necessary (para 4-19).
Replace a defective high tension cable (4-18).

Connect positive lead of multimeter to condenser terminal lead.
Set multimeter to highest resistance setting and zero meter.
Connect second lead of multimeter to ground while observing meter.
If meter shows a deflection, then goes to infinity, then go to next step.
If no deflection occurs or does not go to infinity after deflection, replace condenser (para
If meter doesnt return to infinity, remove connection between points and condenser and
