Question about Briggs & Stratton Briggs Stratton Intek V - Twin Vertical Ohv Engine with Electric Start 22 Hp, 1" X 3 5/32" Shaft, ModelNo. 44K777 - 0027 - E1
Craftsman riding lawnmower, briggs and stratton 24hp v twin. fuel tank under the seat. has fuel pump above one of the valve covers,( how does that work?). replaced fuel filter but it still starves for fuel. Surges and cuts out once in a while under a load.
Any help with this would be a great .
Your fuel pump is diaghram actuated by pulses from crankcase pressure, if you look there is a small tube that runs from pump to valve cover, pull fuel line off carb and have some one crank it over to see if it's pumping. could be pump or blockage between tank and pump, if fuel flow seems good to carb, i would pull bowl off and check for dirt and also make sure anti run on valve, the thinghy that holds the bowl on to carb is opening properly, it should open and close when you turn key from off to run, beyond that it could be you have some water in your gas.

Did you bring the mower from another area? Could need jetting for your altitude.

No doubt high elevation Colorado residents did re jet their cars to use LEANER jets due to less oxygen in the air, i.e. thin air.
I plan to plumb in an outboard fuel primer bulb to pump when ever the engine stalls / starves,until we can make a more informed decison.

Had the same problem with an almost new Craftsman w/ Intek 20.0 HP. Check all the "usual suspects" and had to have a tech come out. He had me start it. It ran for a few minutes and stopped (per usual). He immediately went to the Anti-Backfire solenoid. It is an electrically operated "plunger-style" fuel line blocker. They are famous for going bad. The part is about $65 and its sole purpose is to starve the engine of its fuel supply at shutdown so it won't backfire. If it is disabled, the user must throttle the engine down for 10 seconds or so before turning the key off in order to avoid backfires. Gee... let's see, 10 seconds of my time each time I use the mower vs $65 part ... No contest! Remove the solenoid, take a pair of electrician side cutters and snip off the tip of the plunger and reinstall it. Problem solved ! ! !
