Question about Briggs & Stratton Garden

Open Question

Classic 450 series Model 90000 will not stop.

Lawn mower starts OK. Will not stop after half an hours use. Have to run it into something solid before it shudders to a stop. Can't do the motor any good. Is it carburretor or ?

SOURCE: Lawn mower will not start and run

Sounds like a clogged carb or a cracked primer bulb. I would install a carb rebuild kit and new primer bulb if your mower uses one.

SOURCE: lawn mower runs well from cold but if stopped won't start

Sounds like it's running rich. If the mixture is slightly rich it will start well when cold, but when hot it floods. Check the air cleaner to be sure it's not clogged/blocked. Get a new plug for it and if this happens again just install the new plug - the new plug won't be fouled with fuel. If it started with the new plug then you're on your way to a carb adjustment (that is if the air filter/cleaner is clean)

SOURCE: lawn mower not quite starting

Sounds like you have dirt and/or moisture in the carburetor float bowl. Remove the bowl and clean it out. place a small pan or bowl under it when you start to remove it to catch the fuel and look for water. It will look like a "bubble" floating at the bottom of the fuel. Get a can of areosol carburetor cleaner with a long tube on it, stick the tube up in the hole where the bowl nut goes and spray it out to remove and fine dirt that may be in there. The following is in CAPS because I cannot stress enough, the safety and hazards of using the carb cleaner:
USE SAFETY GLASSES/GOGGLES AND BE VERY CAREFUL USING THE SPRAY - - IT WILL BURN YOUR EYES AND IF YOU HAVE SENSITIVE SKIN IT WILL BURN THAT TOO

There should be 3 safety switches on the mower. 1 will be under the seat, causing the engine to die if you were to fall off the machine while in gear. 1 is in the transmission to be sure the machine is in neutral when you go to start it, and one will be on the blades to insure they are not engaged when you go to start it. You will not want to bypass this switch, rather get it replaced as it is very important that this safety feature is working should you slip off the seat or accidentally get off the machine when it's in gear.

My Briggs & Stratton 450 Series Lawn Mower Engine starts after priming but stops almost immediately as if it is not getting fuel


The primary jet is probably clogged. If you remove the fuel bowl and float assembly you should be able to slide a fine wire through the orifice to clean it. Rinse everything with carb cleaner before reassembly.

The engine stops after a half hour of mowing and will not start until it cools down, after which the cycle repeats itself


engine getting hot. Take rope pull off and clean off all the air fins on the cylinder block, use air how and do a good cleaning. If flywheel still have all the cooling fins it should help the problem or even solve it. Keep mower airways clean.

Hi I have a Craftsman Lawn Mower 225 and i bought a 40w oil and put in it and it started leaking and ommiting huge white smoke. what should i do?


Hi Manny First thing is Drain all the oil back out. You have most certainly overfilled it. Try and get as much out as you can from the same place you filled it from. Leave it tilted back until it stops running and then put the mower level for half an hour. Check the oil level now and clean the spark plug and replace it. There will still be oil in the air filter due to over filling. Only put oil in one egg cup at a time until its below max on the dip stick. Run the mower for 20 minutes and burn the smoke off. It may smoke for a few times but thats ok.

Ran over somthing with lawn mower now it wont


You're right to check the flywheel key - are you certain it's ok? Also our instinct is to tip the machine over to clear the obstruction, which can send oil to places it shouldn't be! Does the machine have compression? It's possible to break the con-rod if you hit something really solid. You can check the piston's still moving by taking out the spark plug and inserting something like a cable tie in the plug hole. As you turn the engine over you should be able to detect the piston moving up and down. The jolt could also have dislodged coke in the engine that could foul the spark plug. Try fitting a new one. Come back to me if none of these solutions work..

Engine won't start . Pour gas in cylinder it starts then quits.


hi lou. your carbeurator is gummed up. It will need to be removed, soaked in carb cleaner for three hours and then rebuilt using the correct kit.

if you are not familiar with how to do this i recommend that u have it done by a lawn mower pro

Stalling


I have same mower and just fixed what seems like a similar problem description. I had gone down the fuel system route and the symptoms just didn't add up. Stopped abruptly w/o sputtering once I reached warm-up temp. Replaced the solid state ignition (34443C now part number 3444D). Problem corrected and just mowed my 1/3rd acre w/ no issues.
