I have already checked the oil alert,coil,cleaned carb...for this model do you have to bleed all the air out to start/restart..also could the throttle be peset to low..because when it does start for no good reason it will put put along..is the throttle under the gas tanks..I see where there is a adjustable screw on the arm where the engine will go slower when fil with air pressure..help...Don

Re: starting problem/turning self off
Follow the copper airline that leads from the compressor to the tank and you will find the pilot valve. This brass valve controls the pressure setting and also controls the engine. There is a small flip lever on top of the pilot valve that unloads the compressor for easy starting when there is pressure in the tank. Raise the lever straight up for start and lay to side for normal run cycle. When the compressor fills tank to set level, the pilot valve pops and idles the engine. If engine stalls raise idle by turning the idle screw clockwise at the carb. The arm that you see under the tank is the governor control arm. To increase the engine speed when pumping turn speed control screw counter clockwise. Sometimes the throtle control cable must be adjusted by loosening the clamp that holds the cable (black cable) at the engine and pulling the cable back away from the clamp and re-clamp. Hope this helps, good luck.

Does not turn over or does not start? Does not turn over usually means a bad battery or starter. Or connections which you have already checked. There may be a fuse block or inline fuse as well. Does it have a manual pull start as well? Does this turn over the engine or is it siezed up, low/no oil.
Turns over but does not fire usually is spark or the fuel. Back firing would guess spark plug or carberator (air fuel mixture) If it turns over but does not fire, try putting in some Seafoam fuel system cleaner. This will get the varnish-gunking stuff out of the carb. Mix in your tank, turn over quite a bit to get it pulled into your carb bowl and into some of the carb port holes. Let it soak a while and then turn over again every so often to pull in new cleaner. If it starts at some point it will stink a little while burning the cleaner in the tank.
Make sure you have check the old fuel lines and and air vacuum lines for pin holes and cracks as well. Change the plugs. Make sure the air filter is clean. Change the fuel filter. Does it fire if you shoot starter fluid in the carb air intake, this would suggest a fuel issue, such as dirty carb, bad fuel line or fuel filter, or fuel pump.
Bleeding is never a good idea when you are a motorcycle rider.
It usually happens when you crash.
As for bleeding the fuel lines (carb) it should not be necessary as the fuel is gravity fed from the tank.
- Since the bike starts when you prime it, but then stops, fuel is not getting through the carb. Sorry for making such a basic comment, but we have to find out why.
- Here are some suggestions:
1) Make sure the fuel valve is turned on.
2) If there is a fuel filter make sure it is not blocked.
3) Make sure that fuel is being delivered to the carb. Turn valve off, disconnect hose at carb and hold over glass container, (that's so you can look at it to see if there is dirt or water in it), turn valve on and collect some gas.
4) If the gas is flowing into the carb but not getting into the cylinders, the carb is plugged and needs to be carefully dismantled, cleaned, and re-assembled.
Sounds like you should be out riding pretty quick.
You will need to bleed air from the injector pump it self. Next to test glo plugs pull from engine and connect a wire to the body to the earth. Turn on ignition and press button for a few seconds and they should glow. If not check for power to the plug
hi there harryandmeli
sounds like you still have a restriction in your carb or the float level is not right
check all the opening s and jets carefully, particularly main jet and emulsion tube air bleeds
and the idle air bleed , and idle jet, is the tank clean and no water ? , is the tank breather working ?, make sure gaskets at carb flange are ok - no leaking of air , make sure air filter is not blocked ?
provided compression and spark ok,( spark should jump a 6 mm gap minimum ) to pass a coil test and fuel flow from tank to carb is good , these engines have hydraulic valve lifters and like 10w/30 kohler oil , everything being = engine should run good
remember F A C T S
F = Fuel , A = Air , C = Compression , T = Timming , S = Spark
Recurring issues with honda engine no start. Engine was thought to be out of gas however engine was actually shut down by oil alert. Check/change oil to reset, or unplug wire from oil alert and check engine. Vacuum in fuel system due to faulty fuel cap. Loosen cap to allow air in tank. Water in fuel. Water will condense out of the fuel in fuel container and will be introduced into tank. Water is heavier than fuel and will enter carb bowl. Check engine fuel tank with flashlight for signs of water, remove fuel bowl (shut off fuel) and clean. Spark plug is rarely issue, however could be wet from too much choke. Good luck
Only tilt a lawnmower backwards toward the handle end (spark plug end raises) Other ways move the oil around to places it doesn't need to go. Now you probably have gas in the oil....check it or change it (milky looking or smells like gas..contaminated...might need changing anyway...You probably will have oil in the carb and it will blow smoke...You probably filled the oil breather with oil and it will drain down...causing smoke also. This was the wrong thing to do A 2 year old unit should be mechanically sound..Check the air filter, spark plug and carburetor for oil fouling. Remove the bowl on the carb to help get some of the oil out...it will leak gas when you do.
recheck float level as well as needle and seat for sticking and or damage, just crack line to bleed air , and eventually it self bleeds anyway... also unless you replaced with new floats check float weight with a float scale to see if floats are saturated or have fuel inside making the heavy and inaccurate ...
