SOURCE: John Deere Gx75, kawasaki 9hp motor- oil in carb!

A very common problem with the GX series with Kawasaki engines. The carburetor 'inlet needle' sticks open and fills the crankcase with fuel. When checking the oil, it can be difficult to see the gasoline and the level appears to be OK. Remove the dipstick and smell the oil, you may detect a gasoline smell. Also, drain the oil, and you may find much more fluid than you expect.
The solution on newer mowers was to install an 'in-line' shut-off valve to keep the fuel from syphoning into the carburetor. The inlet needle and seat in the carburetor is NOT replaceable, so a new carburetor is the ultimate solution, but VERY expensive. Installing and using an in-line shut-off valve is more affordable.
Also, this situation is common when machine is transported on a trailer, as the bouncing causes the needle/seat to leak. When transporting, always turn off the fuel supply to the carburetor.

Hi


Unhook the fuel pump feed to carb line and place it over a gas can with ignition disabled to see if it is pumping any fuel at all. If you are getting fuel past the filter and pump (should be low pressure) your next bet would be to check the carb itself. Many smaller motors that aren't run often can develop deposits or contaminants that clog small ports or jets in the carb and prevent fuel from making its way into the motor. If you have any available you may want to try spraying a little starting fluid into the carbs while cranking to see if it will help it turn over.

However if you are getting gas out of the bowl, then it can't be a plugged fuel filter. It could be bad needle-valve or blocked passage. Take the carb apart and soak it overnight in Lacquer thinner then blow it out with an air compressor. The float should be set slightly higher than level with the carburetor upside down.

SOURCE: John deere gx345 has no spark at plug what is the cause?

need new coil pack or have short in harness grounding engine from running. check fuel line to carburator. 1. take float bowel off bottom of carb. do not touch float or pin holding float. crank engine over until fuel comes out of carb. If fuel comes out, you don't have fuel problem. put float bowel back on carb. 2. check for spark. take spark plug out of mower. put wire back on plug and place the threads on head [or metal of engine to ground the plug]. crank engine over for a few seconds to see if plug gets spark . [always double check with another spark plug that is good]. [[ Remember!!! you have to have someone sitting on the lawnmower to start. unless you by-pass safety switch [only do this if you understand how the safety switch works. NOT EXPLAINED HERE!!!]] If spark is present, there is no grounding problem. when engine is cool. 3. CHECK COIL PACK. for continuity. When the coil pack gets hot it will stop any juice to the plug. A>Check temp sensor B> Check Safety switches grounding out. C> Check for cut wiring harnes. [loose wires rubbing against pulleys, wires cut by rodents]. Hope this helps.........................GAS

My john deere 245 lawn tractor will not start only backfires out the muffler.


There are 2 likely problems.
First spray a prime in the carb and see if the motor runs on a prime. If it does then you need to remove your carb and clean- there is likely water in your fuel.
Second- check for a sheared flywheel key.
