Section 02 TROUBLESHOOTING GUIDE
Subsection 03 (FUEL AND OIL SYSTEMS (2-STROKE ENGINES))
Symptom: HIGH INJECTION OIL CONSUMPTION.
1. Check oil injection pump adjustment.
- Oil injection pump adjusted too rich. Adjust.
2. Check injection pump identification.
- Wrong pump installed. Replace with the appropriate pump. Refer to OIL INJECTION SYSTEM.
3. Check injection oil lines and their fitting.
- Leaking lines. Replace defective part(s).
4. Check injection pump cover gasket.
- Worn gasket. Replace.
5. Check pump check valve(s).
- Check valve(s) stuck open. Replace.
6. Check pump.
- Leaking pump. Replace.
7. Check oil pump cable.
- Cable stuck in open position. Replace cable.
8. On liquid-cooled models, test pump shaft gear reservoir for leaks.
- Leaking seals. Replace seals.
Symptom: ENGINE LACKS FUEL (OR LEAN MIXTURE).
1. Check fuel filter ball located in fuel tank. Ball must move freely.
- Corrosion due to oxidation at installation. Replace fuel filter.
2. Check if lines are perforated or kinked or if they leak at fittings.
- Lines are too big for their fittings or are improperly routed. Replace or properly relocate lines.
3. Check fuel pump outlet flow.
- Dirt clogging fuel pump lines or torn membrane. Clean or replace fuel pump.
4. Check needle valve of carburetor(s).
- Dirt (varnish, foreign particle) clogging fuel line inlets. Clean.
5. Check main jet.
- Dirt (varnish, foreign particle) accumulation at main jet. Clean.
6. Check float height in carburetor bowl(s).
- Running out of fuel at high speed because float height is too low. Adjust float height according
to specifications.
Symptom: DPM SEEMS TO BE DEFECTIVE.
1. Check electrical connections.
- Corroded terminals. Clean or replace.
2. Fuel mixture is too rich or too poor.
- Possible damage to DPM. If DPM does not operate properly, unplug compensation solenoid
connector while engine is running. The carburetion is now identical to that of carburetors without
a DPM, provided that all pipe fittings are tight and that solenoid is in good condition, (it must not
be half-open). If problem is resolved with this procedure, DPM is faulty.
