Kawasaki FB460v Surge

Just bought a Ariens w/Kaw 460v. Runs great without the air cleaner. As soon as you screw the air cleaner downs it starts surging. I cleaned the vent hole beside the vent tube and that didn't help. Any ideas? Thanks

Is that a new air filter you are installing ? I have seen filters that appeared to look ok but were in-fact partly clogged.

No the filter isn't new. It does look clean. When the blade is engaged and I am mowing is seems to do good. If I kick out the blade it starts running rich and surging. I will get a new filter and try it. Thanks!

Sounds like debris in the idle air circuit side of the carb, I would give it a good tear down and clean out with carb spray and compressed air.

If you do find trash in the carb clean the tank and flush the fuel line also then replace the fuel filter.

It may be that you have an aftermarket air filter. They look just like genuine Kaw air filters, but they don't last. They clog up in no time and you have to replace them. I'd replace it with a genuine Kaw air filter.

Hi Tibbs,

I had this very same problem some time ago w/460. EXACT same symptoms.

You have a Bad/Leaky INTAKE VALVE. You can either change the valve and polish the seat w/ lapping coumpound OR Cut a 2" wide opening in the base of the air filter houseing, just behind the stock 1/8" air slot. Put the cover on and engage the blades.....SMOOTH

This one drove me nuts for weeks before I got this one

Pete D.
