Tried pouring fuel in spark plug hole engine start but when fuel is burned out it kills. Primer bulb is hard like it has fuel in it. Fuel was ran dry when engine was last used, maybe sat for about a year.

Re: How can I get this engine to keep running?
Pull the carby and have it services as the diaphragm has gone hard and not working properly
you may have to replace the filter on the end of the fuel line in the tank as they will go hard if left with out fuel for a period of time.

The best way to check the switch is to diss connet the kill wire from the ignition unit itself, this will rule out the switch and the wireing up to the switch, with it diss connected remove the spark plug, place on the top of the cylinder and check for a spark by cranking the engine, keep the plug away from the plug hole when doing this. as for the fuel hose, the pipe should be long enough to come out through the filler cap hole, bend a loop in the end of a peice of wire, use this to hook the filter and hose to pull it out.
Hi There, Check the primer bulb for tare or pin holes. Replace it. Check and clean carb jet it maybe plugged with debree. Also check for spark which you didn't say. Replace with correct plug.
Note; Do not use strong cleaners on rubber seals (O rings and gaskets) They dry up and crack.
If needed use a dabble of grease on seals
Remove spark plug and check for spark (plug base to engine metal)--it should be blue and snappy with a fresh plug gapped at 0.020". If looks ok, pour a little fuel mix into the plug hole and try for start. If it pops several times, you have fuel delivery problems. Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. When the carburetor was apart, did you note the condition of the diaphragm in the lower chamber--it should be flexible with no holes or cracks. Does the primer bulb fill with fuel when pumped several times? Hope some of this helps!
After 3 years, the fuel lines may start to decay and the fuel filter in the tank is likely to be plugged. Check the air cleaner and muffler for plugging also. Remove the spark plug and check for spark which should be blue and snappy. If nothing, try a new plug gapped at 0.020". A properly running two-stroke plug should have a light to medium tan color on the interior insulator. A black insulator indicates an overly rich fuel mix or jet setting. A white insulator is either new or running too lean which will damage the piston and cylinder if allowed to continue to run. If you get spark, pour a little mixed fuel into the plug hole and try to start the engine. If you get a few pops, then concentrate on the carburetor and fuel feed. Does the primer bulb bring in fresh fuel when pumped? If not, is the bulb itself damaged or hardened? The primer is supposed to pull fuel through the filter, into the carburetor filling all spaces inside, then out to the primer pump and the excess returned to the tank through another line. Hope some of this helps!
Test for spark at the plug--it should be blue and snappy. If nothing or weak spark, try a new plug--if no help, take the machine back for warranty service. If you have good spark, pour in a small amount of fuel mix in the plug hole, and reinstall the plug. If you get a few pops, then it has fuel delivery problems. Check the fuel lines for proper connections including the line and filter in the tank. Does the primer bulb fill with fuel when pumped? Make sure the carburetor is tight to the engine. Anything beyond these checks should be addressed by warranty service. Hope this helps!
drain fuel tank. keep depressing the primer bulb until it is clear. drain tank again. remove carb cover and disconnect lines one at a time. keep depressing primer bulb to get rid of excess gas. remove spark plug an turn engine in a position that the spark plug inlet is facing the floor, pull starter rope a few times to get rid of gas in the engine chamber.
Remove the fuel filter and fuel line and replace then try it, if it still does not stay running you will have to change outthe primer bulb. If you need more innformation let me know. Aslo please rate this as this is a free service and thanks for using Fixya.
