Sounds like an air leak... either at the base gasket or the reed valve gasket. or the carb/reed intake boot...MAYBE THE HEAD GASKET...

...AND ... get a qualified pro to look at your carb..tell him which parts you replaced...

SOURCE: low power stumble at idle to low rpm

try placing the reed spacer between .reed assembly & cylinder, also try an adjustable ignition stator plate, set at +4, k & n air filter, open air box.replace T.O.R.S. eliminator system w/ a cap & cable, and idle air screw install kit, also a pipe tuned for more torque(bottom -end/mid range) blasters dont have a lot of power on bottom end and the engine needs to rev to hit power band.cylinder porting,240 bigbore kits, & +4mm stroker crank assemblies are good performance options.

SOURCE: carb problem

With the symptons I think you need to clean the carburator , it seems it doen't get the fuel at all, thts why you hve to spray the carb cleaner to start it !
Remove the bowl of the carb and see if theres fuel coming in once you switch the petcock to 'ON' postion, if it is coming thn prolly the float is too tight (whn the bowl was fitted) thus not allowing the fuel into the float chamber, you will need to adjust the float.
Check the condition of the bowl inside if it has the rusty powderish residue, it will require cleaning and blowing off the jets both the poilet and main jets.
Good luck.

SOURCE: 2003 sportster wont start or run right when it is warmed up

this may or may not be the same as mine, but I have an 03 XLH 883 and it comes to find out that the Ignition location and componeets is a lot different in most models. Finding parts and information has been a travesty at best. First thing is, everyone uses a different name for the same thing. On my model as it turns out, the Crank/ Cam Positioning Sensor is the same as the Ignition Module. On other Bikes it is mounted elsewhere. From all the reading and searching I have done, each of the symptoms are slightly different, as well as components mounted in different locations. unfortunaly there is alot of confusion on this topic even though it seems like it is fairly common. the new module was quite difficult to locate and replace. PLus the directions/ wiring are quite vague and cloudy. The first Module has 5 wires but the new one only has 2. It is not clear which wire goes to which side of the coil, so be careful when you hook it up...

SOURCE: wont start by kick start but will by pull start

it could be the gaskets around your carb are bad and leaking air if so its thinning your gas fumes with more air then what is needed inside your combustion chamber witch is causing your engine to stop running like that. best of luck

Why will my arctic cat 4 wheeler not turn off when I turn the key off

If it carries on running as though you haven't turned the key, there can only be two reasons. Faulty switch, or faulty earth somewhere.

If is falters, carries on a bit and then stops, usually caused by carbon build or which is glowing hot and igniting the mixture after the key is turned.

2006 arctic cat wont start

If you've got decent compression, spark and fuel and it wont run - what about about air? Clean / new air filter installed? All 4 are needed to run.

While riding my oil filter came loose and i lost about half my oil. The bike stopped running but would turn over just fine. I put oil back in it after tighten up my filter but it still wont start,

Have you checked to see if you are getting spark at the plug? Look in your manual to see if there is a low oil pressure safety shut down switch that has to be reset.

My Suzuki Eiger 400 starts hard then once running is great.

The carburetor choke valve might be stuck open or not closing when the engine is cold. The engine needs a richer mixture to start. Too rich a mixture (flooding) can also cause trouble. Turn the fuel valve off to be sure the carb isn't leaking when not in use. If it smokes black on startup, it's flooding. Also check the condition of the spark plugs.

change oil ? water wont compress!!! prolly gallded all internal parts . at this point i would try transmission fluid. drain oil and check for metal or allum. shavings. refill w/trans fluid , remove spark plug , add tfluid in very small amt to cyl. replace plug.start briefly dont rev eng at all . let idle if it will. maybe 1 to 2 mins. shut off let complete cool down . restart again w/same fluid. same as b4. stop drain fluid . smell t.fluid if burnt or not. flush cranckcase w/new oil. hope for the best here. refill eng to proper level and p++ y. has worked for me but wasnt severe as yours sounds to be. good luck let me know if it helps or not. be sure ALL TRANS FLUID IS GONE FROM ENG. B4 new oil is put in . replace oil filter too b4 trans fluid is added and after tfluid is emptied.
