B- Troubleshooting Tips - engine will not idle:
1- Improper idle mixture or rpm setting.
2- Intake manifold air leak.
3- Malfunctioning automatic advance mechanism or other ignition problem.
4- Foreign material in air or gas passageway in carb causing gas flow restriction to idle or intermediate circuit. Picture 41 shows
intermediate air bleed metering hole. Picture 41 shows intermediate jet metering hole. Clear holes with compressed air.
Do not use wire or drill to clear hole. If size of hole is altered, starting system will be altered and carburetor bowl irreversibly damaged.
Compressed air and particles dislodged by compressed air are potentially harmful to eyes and body. Wear protective goggles when using
compressed air and always direct air stream away from yourself and others nearby.
5- Enrichment/fast idle plunger not seated causing excessively rich mixture. Be sure enrichment lever is fully disengaged (in down
position) allowing plunger to bottom and seal passageway. Remove air cleaner backplate. Lift and release plunger several times, letting
it "snap" closed to fully seat against carb body. When backplate is reinstalled on carb, be sure lever is engaged in plunger properly and
that plunger is not lifted as mounting screws are tightened. See Picture 20, page 11.
6- 1⁄4" insulator block between carb and manifold omitted. Heat transfer from manifold to carb may cause temporary rich condition at idle
and low rpm when engine restarted after being shut off for 10 to 20 minutes. Install insulator block to minimize heat transfer.
C- Adjusting Intermediate System - (See Jetting Chart Page 23) Intermediate range is used most often under normal riding conditions. It
controls fuel delivery from just off idle to approximately 2500-3000 rpm or 55 to 60 mph depending on gearing. Close attention must be
paid when selecting intermediate jet to achieve optimum performance and best gas mileage. Intermediate jet (See Picture 42), is reached
by removing float bowl assembly. Size of metering hole in intermediate jet is stamped in thousandths of an inch on end or side of jet. Size
of intermediate jet installed in new carburetor from S&S® is indicated on tag attached to carb or on printed label on carburetor packing box.
Keep this information handy for future reference, especially when contacting S&S Technical Services Dept. for assistance. It is a good idea
to record any jetting changes for future reference.
