Just replace a head gasket on a ELS 500 Briggs 18.5 single cylinder, and adjusted valve cleance to .004 thousands 1/4 inch into power stroke cycle top dead center. sounds like the rockers are ticking really bad. I did the same exact thing on a different /same type motor, on runs great. Only other thing i did was replace the carb seat and needle. It just sounds like the valves betwwen the rods and rockers are set to loose, but like i said i set them the same way i did on the previous engine, and its working fine. Any one have any opinions they would like to share.
Incorrect method of setting valve clearance find tdc with the valves rocking, exhaust just closing and inlet just opening--- known as valve rock-- now turn 1 full turn and both valves will be fully closed
adjust the clearance to .010" inlet hot and .012" exhaust hot the noise you hear is clearance too wide

This is a common problem. The needle and seat are prone to being held open from debris, old fuel (these days it only takes a month for fuel to start to go bad) and poor mower design. The weight of the fuel from the tank can be enough to overpower the float system with just the slightest "gumming" of the needle seat. Also, if it's equipped with an electrically powered valve on the bottom of the float bowl, this unit can outright fail, get gummed up a bit, or the electrical system have a problem and power is getting to this unit while switched off, leaving it open thus passing fuel. Most likely, replacing the needle and seat, giving the carb a good cleaning will solve your problem, however if there is damage to the seat from age or debris, just install a 2 dollar in line shut off valve available at most retailers. Then just turn the fuel on and off manually. Cheap fix. 2. Drain the oil from the engine, refill with new oil and just a oz. of atf (automatic trans fluid). Crank the engine with plug wire disconnected for 30 sec or so, then connect the plug wire. Start the engine, but only let it run near idle for a minute or so. Drain again, letting the crankcase "air out" with all plugs\dipstick removed. Remaining fuel will evaporate. Refill and your off and cutting......The ATF is a detergent of a type and will help to collect the fuel from the surfaces inside the engine. It's important to note the fuel will have washed any lubrication properties from the oil, and damage to the journals and other surfaces can happen if the engine is run too long. Usually following the above procedure will limit damage and the engine should be good for many more seasons. Good luck! Papa

if your oil level is to high it will do this. i would drain and refill the oil to oem specs slowly as not to overfill so it doesn't blow over the top of the piston.hope this helps

CHECK YOUR FLYWHEEL KEY FIRST also check to see if your blade is loose, sounds like a timing knock to me
Testimonial: "Most helpful, When I took the blade off it was not up to the required torque of 55 ft lbs and the fit of the hub and keyway was not tight. "

Exactly how much oil is it using? Is it blowing wite or blue smoke whe you are running it?
Typically, with the engine running at full throttle, an air cooled
engine can consume up to 1 oz. of oil, per cylinder, per hour.
When you had the heads off and looked at the cylinders, were there still hash marks from the factory honing process or were they shiny and no hash marks? If the hash marks are still visible, the cylinder is okay but if they are shiny and smooth with no hash marks showing, you need to measure the diameter of the cylinders to see if they are badly worn and in need of further repair
I have found on several occasions with the Intek V twin, if the dipstick is not properly seated, there will be a crankcase air leak which will also cause excessive oil consumption. When you put the dipstick in its tube, be sure that the symbol is right side up when in the fully turned position, also verify that the o-ring is in place and good condition. Look at the inside of your dipstick cap to see if there is a lot of "oily dirt" accumulated there, if there is, the dipstick has been inadvertently installed wrong.

not hard and no dont need to remove intake will have to remove some things depends on which side your working on like air intake hose a wire or two might have to unbolt a/c/ if u have- could be rocker also check for dry push rod ,weak valve springs worn valve guide-
