SOURCE: Briggs & Stratton engine on Murray lawn mower

I always replace the air filter if its a paper element, and even if its a foam element I replace it rather than clean it. That said, engine stumbling is rarely and air flow problem - but it could be, so having a new filter assures no air restrictions.

I would drop the carbuerator bowl. On the bottom of the carb, near where the fuel line comes into the engine, should be a nut. Removing this nut allows the bowl to drop off the carb. Some engines the bowl screws off, you will have to look at the bowl. Often the bowl has sediment or sludge buildup inside. Cleaning the bottom of the bowl can prevent that sludge/sediment from plugging the intake tube. Even on newer mower models this is a common problem, the gas line tubing interior breaks down and the inside of the tubing can start degrading - ending up in the bowl as sludge.

After cleaning the bowl, I would add one ounce of fuel line cleaner to a full tank of fuel and run the entire tank of fuel. This will clean any deposits or "varnish" from the interior carb parts. Doing this and the first step will assure your carb is clean and functioning.

If that doesn't help, then I would look at the spacing between the magneto and coil assembly. If you want to do that I'd like you to write down all the model numbers and serial numbers on the engine nameplate, that way I can give you specific directions.

Hope this helps,
Gregg

A lot of time when the small motors on these push mowers surge it is a governing spring that is weak or broke. It does not hold enough tension and causes the valve to fluctuate. I have fixed this many time for a relatively cheap amount (under $5).

SOURCE: Briggs and stratton engine surges and slows, repeatedly

There is still either water or debree contaminating the fuel system. Surging is usually debree, empty and flush the tank with gas or Iso alcohol, disassemble carb soak in solvent for 30 minutes blow out the carb passages, reassemble and if the problem persists run engine at top rpm with air cleaner off and block off carb intake with hand, this will stall the motor restart and repeat 4 - 5 times this wiil draw out any debree or other blockage in the carb.

SOURCE: 4.5 hp Briggs& Stratton push mower will not run

You need to rebuild your carb. The diaphram in the carb has gotten hard and is no longer acting as a fuel pump to pump the fuel to the carb. Get a rebuild kit and a compressor (for compressed air) to blow out the jet passages. It is an medium to easy job, just watch the small parts. ----------------------------------------------------------------------------- Hint: Before you remove your fuel/air jets, bottom them out first and count the number of turns it takes to bottom them out and mark it down for each fuel/air jet. When you go to reinstall the fuel/air jets bottom them out and then back them back out to the number of turns before removal. That way the fuel/air jets are set to the right number of turns when it was running right. Good Luck, I hope this helped Please rate me...Thanks

Briggs Stratton 5hp I/C starts ok, runs, but will not rev


My money is on a partial blockage of the main jet or the passageway to it. You're having to force it to run through the idle jet by fully choking the incoming air. There's not enough gas coming in with the choke open to allow it to run.

I'm thiniking total carb disassembly, carb cleaner and an air compressor combined with a ton of patience will take care of the issue.

Were is the caburetor jets


depend on the engine. some briggs have the carb mounted to the gas tank. If your equipment is older, say about 20-25 years old the carb may have screws(idle mix, high speed mixture). Sometimes the main jet is the bowl nut.

Stills sounds like a carb problem to me. Did you make sure all the jets were clean and open? Some of these carbs have a main jet adjustment screw on the bottom of the carb, if yours does try opening it up a 1/4 turn at a time to richen the fuel mixture until it runs properly.

I have a Briggs & Stratton 5HP Engine (Horizontal shaft) And it has the diaphragm carb on it. The last person to own it messed with the carb adjustments and it'll have trouble starting and idling...


2 turns out should get ya started adjust from there. If adjusting doesn't help you may need a new diaphragm. While you have diaphragm out blow through the 2 holes you'll see under diaphragm with air to hopefully avoid pulling carb off to clear screens on pick up tubes. Also check carb mounting screws through carb into tank. They frequently come loose on chippers and log splitters because of hard mount.

Craftsman 19.5 HP Briggs and Stratton engine. Will not start. will start with starter fluid and then stalls. It appears no gas is getting to the carb.


disconnect fuel line from carb and crank engine. NO FUEL-check in-line fuel filter, kinked line, trash or water in bottom of fuel tank. FUEL- gas is stale, has water in it, or carb has sediment in bowl, bottom jet or idle jet.or float could be stuck shut.

Need carburetor adjustment


I had a similar problem with my 23 hp briggs. While cleaning the carb I found that the great gas we get today had eaten the seal around one of the jets in the throttle body causing it to fall out. Replaced the jet and now runs like a champ. Hope this helps.
