Troubleshooting; Snow Blower - Honda HSS724A Owner's Manual

With the engine and exhaust system completely cooled, cover the
snow blower to keep out dust. A hot engine and exhaust system can
ignite or melt some materials. Do not use sheet plastic as a dust
cover. A nonporous cover will trap moisture around the engine,
promoting rust and corrosion.
Removal from Storage
Check your snow blower as described in "BEFORE EACH
OPERATION" on page 5.
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the
engine may smoke briefly at startup. This is normal.
