What does it mean when black smoke comes out of the muffler of your 6.75HP push lawn mower?
your fuel mixture is too rich it may be time to change your spark plug and/or air filter. a bad spark plug will not burn all the fuel correctly and a clogged air filter will not provide enough air for a good air/fuel mixture. Actually it depends on what color smoke is coming from it. Black smoke is fuel, however, blue smoke is oil, broken ring and such
No you can't use a golf cart mower on a lawn mower. You have to find a muffler that matches the make and model of the lawn mower.
Many times it just means that the mower has been leaned over on it's side too far and oil has gotten into the breather. It will burn this off after a while. If it persists then you have an internal problem in the engine and are getting alot of blowby into the breather.
A sheared flywheel key (advanced timing) will often cause a red hot muffler. This happens when the mower blade hits a stump, rock, etc.
a manul to show me the way to do it
Answer It could be that you need a new muffler. After so long the baffling inside the muffler can burn out. Also make sure that the muffler is not cracked or that exhaust is not leaking before it gets into the muffler. At the gasket between the muffler and the engine. Hope ths helps.
It just unscrews from the motor
white smoke is usually due to large amounts of oil in the muffler. if the mower was turned on its side for a period of time the oil will run into the muffler and when you start it it burns the oil out. after the large cloud starts to dissipate the smoke should start to change to a normal blue color and then disappear as it clears out
Yes, and very often. The internal baffles are very prone to corrosion due to accumulation of moisture inside the muffler
1. tipped on the muffler side or 2. blown engine
If its black smoke you are burning oil possibly due to oil getting in your exhaust by tilting the lawnmower on its side or your rings are allowing oil by.
What causes a 16.5 hp Briggs and Stratton MTD mower backfire every time it is shut off after mowing the yard?
possible cause The muffler is extremely hot after mowing, when the ignition is turned off, the fuel air mixture continues to be drawn into the engine through the carburetor and when the engine comes to a complete stop the fuel air mixture is now stalled and what is in the muffler is ignited by the header pipe, muffler or exhaust valve. The loud bang is the unmuffled explosion of the air fuel mixture.
only 2 ways! 1- away from the spark plug ^ v. 2 muffler toward the ground < >.
The float on your carb is stuck down and letting gas flow into the oil thru the cylinder pass the rings and out thru the muffler.
Bad piston rings, oil level is too high, check the oil level and adjust
The Honda Black Max self-propelled mower sold a Sam's Club is made by Husqvarna Outdoor Products. No mention in the owner's manual, but the deck plate has an HOV label and the oil that comes with the mower is HOV 4 cycle oil and the label on it states that it is made by "Husqvarna Outdoor Products".
I'm having the same issue. I'm trying to replace my front axle and I need to remove the muffler to get to the axle bolt. Please help. I recently replaced the front axle on my STX38 so I took off the muffler as well. The muffler's heat shield needs to come off first, I think there's just two bolts holding that in place on the front of it. If I remember correctly, there were 4… Read More
If it is a 2-stroke engine, the oil/gas mixture has too much oil. If it is a 4-stroke engine, the oil sump is overfull.
What does it mean when your 15.5 hp Briggs and straiten engine leaks gas and oil out the muffler on a riding mower?
sounds like you have a bad valve guide and or valve seat allowing the two fluids to escape past the valve and out the muffler. also I would do a compression check to see if your rings are bad.
When you turn it off the igniton (spark) to the plug stops as the engine rolls to a stop unburnt fuel collects in the muffler and is ignited by glowing bits of deposits.
You are either using the wrong muffler or the threads are pretty much well gone. If the problem is that the threads are worn, u can use a strip of aluminun foil to wrap around the thread similar to how teflon tape is used to seal thread on pipes.
its burning oil :(
Why is your sears riding mower model 917.2 71821 spewing oil and smoke after you changed the oil and jacked it up to change the cutting blades?
Some engine oil has entered the muffler when the mower was tipped, it will burn off after you run it, make sure the oil level is correct (don't overfill) as this can cause similar problems.
It is probably a stuck needle valve for the float. Look under the carburetor for a round metal bowl with a bolt on the bottom. Unscrew the bolt and try to move the float up with your finger.
L A Burr was a black inventor of the lawn mower. in 1889
Well i have a craftsman 22HP riding mower, and i took the muffler off but left the pipes on just to see what it would sound like, and it popped a little but its not going to hurt it. I actually got better gas mileage and it ran a little better. Basically its like Straight piping a Truck, the motor is just alot smaller. So it's fine
The primer button on a Troy Built 650 self-propelled lawn mower is a black round ball. It is located on the right side of the mower just below the black rectangular fuel tank.
no ,no plug comes pregaped set it at 32
Oil coming from muffler on Briggs and stratton lawn mower engine - primed with gas - why does it fire then quit - brand new engine?
If it is a brand new engine take it back to where you bought it. Because if you do anything to you will void your warranty.
I believe that deck uses sealed permanently lubed bearings.

Hook up jumper cables to a different battery, stick the black cord on the frame of the mower to ground it; touch the red to the starter bolt and hold it there until it starts.
Will a bad muffler make a lawn mower engine run rough. I replaced the solenoid. At one time there was gas in the oil. I'm stumped. The motor sounds like it runs a t idle speed but no difference when I?
If you have oil in your gas it might be over fuelled. The fuel will go past the rings and into the oil. You should see black smoke out the exhaust if this is the case . Your motor will run ruff if the carb. is not set right.
It depends if the smoke is blueish it is burning oil .I it is black it is usually over fueled.
It was most likely a goat or sheep so it could be gray black or white.
The first thing to do is to check the oil level to see if it is over full. Sounds like the carb float vavle may be sticking and you might be getting gas in the oil.
This question makes no sense, gas is gas, regardless of where it comes from.
Was wondering if you could tell me why the two black wires coming out of the ignition switch on my riding mower get hot when i start the mower?
your starter is pulling too much energy from your battery. Either the battery is too small or your starter needs attention.
I don't really know, but ask at a hard where store.
Sounds like you have a weak spark or a fouled plug that is not burning the fuel completely and the fuel is escaping into the muffler via the exhaust valve. This could be dangerous (heat + fuel = danger). Check the spark plug, the spark plug wire, etc for a good spark - the contacts on the magneto could be dirty or rusty too. Another reason could be a stuck fuel float in the carburetor… Read More
The lawn mower was invented and named after Mister Gary Mower.
A typical riding mower with a 38" deck probably comes with a 12.5HP motor. If your mowing requires cutting higher grass or big hills you may want to have one with a larger engine more like a 16.5HP.
Small engines are loud because it would require a large muffler to make them quiet. There is simply not enough room to install a large muffler. This is especially true with 2 cycle engines in trimmers or blowers. The design of a 2 cycle engine contributes to the noise. This and pollution is the reason 2 cycle engines are being phased out in favor of 4 cycle engines.
oil starts out clear or light brown, as combustion gases and dirt particles accumulatethe oil darkens, if it is black it's time to change it
What is wrong if gas leak from vent hole of gas cap on lawn mower even after caps have been replaced It is so bad that gas runs down over tank and to muffler area?
If the vent is on the top of the cap, it would indicate that something is causing back-pressure inside the tank. Get it serviced.
I have found that if you "roll off" the drive belts underneath first there are no problems with just undoing the 4 bolts that hold the engine to the mower chassis, disconnecting the throttle cable from the engine and the whole lot comes off very easily.

This engine will have some good horsepower. It will not be as strong as like a car but it comes pretty high for a lawnmower.
