Hi
I have been working on my carb today,the pipe from the bottom of the carb should just run down by the bottom of the swinging arm,there should be another pipe from the pipe on the left side of the carb just above the fuel intake which also runs down to the swinging arm and connect to nothing.
Cheers

SOURCE: Kawasaki Mule 3010, keeps getting flat battery, wont jump start

Sometimes when the battery keeps going dead like that, a component may be creating a current draw. you can do a simple current draw test with a fluke meter by setting the meter to read amps, make sure the test leads are in the proper portals on the fluke for an amp test, and disconnect one of the battery cables and connect the test leads in-line with the battery and cable. It would help to know you have a good fuse inside the fluke. They are easy to blow, and whatever you do, DO NOT try to start the unit with the meter hooked up for the amp draw test. That is how fuses are blown. With the key off, check for any amp draw. If there is, you can start unplugging components until the draw goes away. If there was no draw to begin with, you may have a stator coil (or alternantor, whichever it has) that is weak and can't keep up.

You need to ensure for the Carburettor Needle fixed, so that the fuel injected out properly, also if the Crank Gasket should be fitted properly.

if you are getting gas, it's probably too much. is it flooding the motor. make sure your float level height is okay and that your float needle valve assembly is clean and not sticking. if you have an electronic choke, try disconnecting it. it might be malfunctioning. also a possibility your valves need to be adjusted.

Check your muffler's spark arrestor screen for clogging. Also test your compression. It needs to be be at least 100 psi for the engine to start.

Have you checked that your float is working properly in the carb? If it is sticking with the plunger shut it will block fuel inlet regardless of having fuel supply?

Have you checked to see if there is definitely fuel in the line at the carb when it's acting up?

Have you made sure that there is still spark when it quits running? You could have something that is grounding out when it warms up and makes it quit firing that while you 'fuss' with gas issues, cools enough to spark then fails again. Hard to say without more details. Also are you sure there isn't a clogged fuel filter in the tank, carb-inlet or inline somewhere?

Recheck spark when the unit cuts out. I am gonna guess you spent a lto of money chasing a bad coil! When a coil starts to go bad they become temperature sensitive. Time does the rest!

Basics to check:
1) Spark plug - brown or dark brown - OK
- aluminum or silver - piston/cylinder scored
a) is it carbon or fuel fouled
b) is there spark

2) Compression - 125 to 150 psi

3) Muffler remove for inspection
a) exhaust screen clean or plugged
b) inspect cylinder wall/piston as the flywheel is slowly rotated

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
ChainSaws:
5) check impulse tube and intake boot for cracks or leaks

*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

Please double check the gasekts/diaphragms for proper installation

Gasoline in the crankcase


If, inside of the carburator the needle and seat does not close (dirt in carb) the fuel will slowly keep pushing through the carb,through the intake into the cylinder then into the crank case.
Do not run this engine until the carb. is rebuilt. The float in the carb.also needs checked to be sure it still floats and its at the exact factory setting.
Also have a new inline fuel filter installed.
Check for dirt in fuel tank.
Keep the air filter clean and in good condition.
I hope this helps you.
