I was able to do it by doing a model and type search for manuals on the Briggs & Stratton site: http://www.briggsandstratton.com/us/en/support/manuals/engine On that page, enter the model and type of your engine, and the cover of the resulting operators manual has the series numbers that match. There are 3 or 4 series listed for your model and type. ...

You could try unhooking the cable at the handle and then tie a loose knot in it. This may make the cable too short. In that case you could drill a hole in the safety handle bail a little further up. I'm fairly certain it's not adjustable at either end. The proper repair requires replacing the cable. Believe it or not, sears.com has an incredible range ...

If the intake valves push rod is bent the valve has come into contact with the piston and is very likely bent. If a valve has been adjusted with an incorrect clearance (too much clearance) or opened up over time due to a loose lock nut.. It can lead to piston/valve contact which will bend the valve. It is caused by the rocker arms ball jumping out of the ...

Is it possible that the rod came loose before it bent and lodged someplace and caused the engine to bend it after it came loose. Am thinking that maybe the adjustment of the rockers was not correct causing the rod to come loose

The cause of the bent push rod is the valve guide thimble is only press fitted, and easily loosens when the engine reaches a certain temp. The thimble then pushes outward, restricting the movement of the valve spring, eventually causing the push rod to bend. This is a design flaw in current B&S engines. I have no idea how long this flaw has been around. ...

More than likely the problem will be solved with a new carburetor. Ethanol gas can plug ports and/or cause float issues. What you are describing is your fuel bowl filling up when sitting still, then you run it but the feed provides enough fuel to not keep it completely filled (or filled to where it's supposed to be). So after a few minutes of running, it ...

If the carb is getting too much fuel, there is one of three reasons, all of them related. The float isn't working. If the float longer floats, it will allow fuel to keep allowing fuel into the float bowl, and therefore the carburetor even when it shouldn't. The needle and seat, which are attached to the float, are not sealing correctly. They could be worn ...

I have noticed with my B&S mower that if i fill the fuel tank too high, some fuel will pass into the housing for the air filter, and it won’t run. I’m careful now to not fill the tank to the top and the problem has gone away. However, I’m not sure that my explanation is accurate (I’m lazy—once a problem is gone I lose interest in determining the cause)....

This is most likely an issue with the carb having issues with ethanol clogging. You may be able to get it work by using something like SeaFoam thrown into the gas tank at a high concentrate. This may entail rebuilding the carb, but I've found it's usually worth my money to replace the carburetor directly due to the amount of time/effort it takes to get a ...

Several things could be the cause with your limited explanation of the symptoms. To further refine things, you should do the following: -check the spark plug and describe what it looks like -check the oil and describe it's looks and level -do you smell gas after the shutdown -how long until it starts again, and what is the engine temp when it starts?

Another possibility is that the valve overheated and then started to seize. This could then cause the bent pushrod without any damage to the piston. can you see any damage to the piston top or the valve? You probably need to remove the valve and check for wear on the valve stem, or a possible bend as mentioned in the other answer. Also look at the valve ...

I think your issue could be one of two things. 1) The float in the carburetor may be fuel saturated. If it is leaking and not closing the needle valve all the way, it could be causing the carb to flood slightly, which would make it slow down a bit when changing the moving vector of the lawn mower. 2) The needle valve itself is not seating correctly and ...

The series is typically on a decal on the engine or on the Operators Manuel You're best bet for verifying a maintenance kit is to get the Model Type and Trim number from the engine and compare the air filter part number on the illustrated parts list on the Briggs and Stratton site. Or, chat a B and S agent and they can find the info for you.

Just a guess, but it sounds like heat-induced vapor-lock to me. You didn't remove any sheet-metal shielding from between the carb and the motor did you? If so, put it back. And clean any airflow ports anywhere near the carburetor, to ensure that the airflow from the flywheel blows well over and around the carb. I'm guessing you're either missing some ...
