TO START ENGINE (See Fig. 3) When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. • Be sure freewheel control is in the transmission engaged position. • Sit on seat in operating position, depress brake pedal and set parking brake. • Move attachment clutch to "DISENGAGED" position. • Move throttle control to choke position. NOTE: Before starting, read the warm and cold starting procedures below. • Insert key into ignition and turn key clockwise to "START" position and release key as soon as engine starts. Do not run starter continuously for more than fifteen sec onds per minute. If the engine does not start after several attempts, move throttle control to fast position, wait a few minutes and try again. If engine still does not start, move the throttle control back to the choke position and retry. WARM WEATHER STARTING (50° F and above) • When engine starts, move the throttle control to the fast position. • The attachments and ground drive can now be used. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above. COLD WEATHER STARTING ( 50° F and below) • When engine starts, allow engine to run with the throttle control in the choke position until the engine runs roughly, then move throttle control to fast position. This may require an engine warm-up period from several seconds to several minutes, depending on the tem per a ture. AUTOMATIC TRANSMISSION WARM UP • Before driving the unit in cold weather, the trans mis sion should be warmed up as follows: • Be sure the tractor is on level ground. • Release the parking brake and let the brake slowly return to operating position. • Allow one minute for transmission to warm up. This can be done during the engine warm up period. • The attachments can also be used during the engine warm-up period after the transmission has been warmed up. NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32 F) the carburetor fuel mixture may need to be adjusted for best engine performance. See "TO ADJUST CARBURETOR" in the Service and Adjustments section of this manual.

Two things, (assuming it is not a Kitchen Range, but a 3kW petrol driven alternator). Don't start it with the load connected. Let it run for a short while on choke; until it starts to run rough a bit, then put the choke to the run position.

You say you cleaned the carb. If you did that by spraying cleaner in through the choke, that's good, but it doesn't get to the root of the problem. The problem is getting the gas into the carb. Try this. drain the gas. Put a small amount of carb cleaner and gas in the tank (about 1:1) Start it up, but don't run it dry. Let it sit for an hour. Then start it up and run the tank dry. Then try just a little gas to see if that fixed it. If not, repeat. Good luck Al K

Clean all the fuel system:lines,carb,etc.. also a new coil will be better.

Fresh fuel? Does carburetor have adjustable jets? Turn the high speed jet (at bottom of float bowl) about 1/4 to1/2 CCW (looking at bottom of bowl). If no improvement, carburetor should be torn apart and cleaned. This also applies if there are no adjustable jets. Is there a fuel filter anywhere?

Generally with two cycle engine as soon as the engine starts the choke needs to be moved to the off or open position. Some chokes have a middle position that lets the motor run until it is warm enough to move the choke into the open position. In other words weather it is a two or four cycle engine the choke is used only to start the engine. If you unit is newer and still does not run well with the choke in the open position, you may need to adjust the hi-speed circuit to a richer one.

vent in gas cap.
fuel filter.
dirt or gum in the carb.???

Where can i obtain a manual for the 5500 gas generator
