I have a Briggs and Stratton 13hp engine on a Toro ride on mower, The engine starts ok but keeps searching and when you throttle down it cuts out instead of ticking over. I have cleaned out the carb but this has not improved the problem. any ideas anyone.

If the engine hunts, chances are the mixture is too lean, and that there is some residual gunk in the carburetor. I have had success with using "Gum-Out" or something similar, added to the gas. The engine will have to be started up and run for at least 20 minutes in order for the solvent to clean up the varnish. It is not a good idea to use these cleaners continually, because they might damage plastic or rubber parts in the fuel system, but it should be OK to use a carb cleaner once a year, or so.

RE: Engine not running

Is it possible that there may be water and debris in the fuel system yet? Is there a good flow of fuel to the carb? Verify that the fuel cap is venting too.
