2oo2 kohler is not getting gas

Does this machine have a fuel filter if so make sure it's clean. Does it have a fuel bowl? Take it off and clean it out real good . also clean the fuel jet. These are why the engines do not start or run properly if one of these are dirty. Dirt keeps the fuel out of the carb.

Kohler engine troubleshooting

Engine hunting is usually down to fuel starvation, this can be dirt in the carb, or the fuel pump is not working correctly, or the anti fire solinoid on the base of the float bowl is not working correctly, you can check the fuel flow from the pump by removing the fuel hose from the carb, place the hose in a suitable container now crank the engine, there should be a good flow of fuel, if so replace the hose, now remve the fuel solinoid from the bottom of the fuel bowl ( place a suitable bowl under the carb as there will be a flow of fuel) switch the igntion on, there should be a click and the small pin in the centre of the solinoid should retract into the housing, if this is ok then there is dirt in the carb so you will have to clean the jets in the carb itself.

Carb needs gas poured in to start engine, after initial start engine will start normally, why?

1) Sounds like the gaskets and/or needles in the bowl are shot or mis-adjusted. That allows gas to run out of the bowl down into the engine overnight. Carb might need to be re-built.
2) If there is gas in the bowl - Is the choke working properly? The butterfly should close completely.

Mower starts after priming, then quits. new sparkplug, air filter etc. cleaned bowl still no luck. cleaned out orifices in bowl screw. nothing. Suggestions?

Evan though you cleaned the bowl, the float isn't "floating" correct in the bowl to raise the needle for gas to flow into the carb. The float and needle can be replaced. When you prime an engine the gas shoots straight to the carb. As when the engine is running the floating goes up and down to raise the needle for gas to flow.

remove the sediment bowl on the bottom of the carb and see how much dirt/contaminent is in the bowl,then lift the float (the metal or plastic round donut shaped object in the bowl) and see if gas runs out,if not then the carb is plugged and engine wont get gas to operate,then you need to try carb cleaner or a complete carb rebuild

Craftsman mower with 20hp B&S Intek won't start/run

That throttle cable issue sounds like it may be the culprit. the cable housing (the outer casing for the wire throttle cable) may not be anchored correctly. Which may be allowing you to move the throttle without any change at the butterfly control on the carb. make sure the cable housing is anchored at both ends.. by the throttle control and at the carb area.. That may be your problem... hope it is that simple...

Cranks fast but wont start

Hi, You did a good job of diagnosing your problem. Gas in bowl and dry plugs, starts with fluid, But, to quote you, "won't go through carb" . If you feel confident, you should disassemble and clean the carb, as that is going to be the problem. As a tip, if the genset is going to sit make sure to turn off the fuel flow to the engine and run till the engine dies. They do not like to sit any length of time with fuel in the carb. Good Luck, this should Fixya!

Mower won't stay running

Assuming it is a B+S engine, if it starts fine and runs rough and smokey as it gets warm and will not get enough speed, the problem is with the Diaphragm between the carb and fuel tank, it costs about £3 and is easy to fit if you have a 10mm and 13mm spanners and a cross heded screwdriver, ver annoying but relatively cheap and simple fix. Max.
