These are idle port screws. They provide air/fuel at low throttle angle but are continuing to provide air/fuel as well at high throttle angle. Backing them out would provide slightly more air/fuel. This doesn't match up with a previously reported rich (fuel smell) condition. Typically you...

The carburetor style is correct. I agree it is not genuine Kawasaki as the numbers would be as pictured below. So, who know what jetting this carburetor has. That could be an issue. What do your spark plugs look like after running in this condition? Are they black with dry soot? You had the...

Ok, if it isn’t Nikki brand or doesn’t have a Kawasaki part number on it, also please check to see if it has a vent tube next to the fuel line inlet.

Hi Tom, Can you confirm the part number of the carburetor? If it is genuine Kawasaki, it will have the part number on top and will start out 15003 or 15004.

I’m not stating that they can’t be filed. Kawasaki doesn’t have a procedure for filing them. It’s a lawnmower engine, not NASCAR.

This set is .020 oversized from the original. They are not file to fit. The top ring is barrel faced the second should be tapered. The paint stripe typically will go to the right of the ring gap on a tapered ring to help with the orientation.

Ah, I for sure misunderstood. Sorry. Could be a switch or a loose connection in the ignition or ground circuit.

My thought is trash in the fuel tank. Try to rig a way to gravity fresh fuel directly to the carburetor. Then see if the issue still occurs.

Ok, that makes sense except the vent hose is exactly that, an atmospheric vent. There should not be fuel in the vent unless there is an issue with the float valve sealing causing the bowl to overflow, as an example. You are correct that the rad screen will not offer much protection. Its purpose...

Who’s to say whether it will work long term. What caused the warpage in the first place and could the plastic be fatigued enough. Hard to say. A fan blade breaking is not unheard of. If it were my 28 y/o engine, I wouldn’t take the chance. A replacement fan is much cheaper than a radiator.

The service spec is .004” - .006”

What did you set the valve lash to? Did you perform the adjustment properly?

@Jimmy the Lock, (you identify as a lock?) You can change your oil every 5 minutes for all I care. Maybe all the confusion is due to you stating the mowers owners manual and I stating the engine owners manual. @StarTech, according to Kawasaki tech training, the engine components are washed...

Can’t believe I am replying to this junk. The Kawasaki engine manual states 100 hours for the first oil change. Kawasaki does not build the mower. If the mower manufacturer says to change the oil daily, that does not mean that recommends it be changed daily. I attend Kawasaki factory training, I...

Please provide documentation as to where Kawasaki signed off on using Amsoil. Please provide documentation as to where Kawasaki has recommended using 10W30 oil. If your manual shows an 8 hr oil change, you received and old owners manual with your 2023 mower. The current manual can be found at...
