Could be 2 things: a restriction in your fuel line/coming out of the tank, or 2: a dirty carburetor needing to be removed, cleaned and possibly rebuilt and reinstalled. Hope it's one of those.Start with pulling the fuel line loose from the carburetor. If you have fuel flowing freely, plug the hose with a golf tee and move onto removing the carburetor. Carb kits are cheap and easy to install. It's best to rebuild while you have it off to avoid similar problems later.

Won't stay running after prime runs out


starving for fuel. first check for bad/old gas, then restrictions in the fuel delivery including fuel line, filter, or buildup of debris in tank or any sharp bends or 90deg. fittings. then pull the float bowl and make sure the float is regulating fuel fuel into the bowl, but most likely your main jet is plugged. use a fine piece of wire like guitar string to runthru the jet located at the lowest part of the carb that hangs down into the float bowl. the jet will be on the side or bottom of this lower piece. put bowl back on, get gas to the carb and recheck starting problem. good luck.

How do I fix my push mower with a Briggs & Stratton engine?


Its obviously a fuel starvation issue, so there is still some blockage in the carb, re move the carb and see if your frendly local dealer will clean it in there sonic cleaning tank, if not soak with carb cleaner and blow the jets through.

Lawn mower will start when primed but will only run for few secon


It starts because of excess fuel from priming. It usually then gets it fuel from main jet in carb.

You need to find the main jet and run a fine piece of sturdy wire through it. That will restore fuel flow so your mower can continue running after the priming fuel is gone.

This is a good thing to learn. Main jets tend to clog a lot on mowers these days.

Mower starts but runs for only 2 secs


What's happening is your carburetor's losing its prime. You may have a leak in the diaphragm, but if you're starting your mower for the first time of the year, it may just have all leaked down and is having troubles pulling the fuel up. Here's what to do. Take the air cleaner off, set it someplace away from the mower, and press the primer bulb about 4 times. Pull the rope, and as soon as it starts to get running, put your hand over the top of the carburetor so that you create a seal on it. You will kill your mower by doing this, but the vacuum from the engine trying to pull air in while your hand is there will fill the carb with fuel and get air, bad fuel, condensation, etc out. You should then be able to start your mower and keep it running. If this doesn't work, you'll probably have to put a new diaphragm in the carburetor, as yours likely has lost its seal, but that's if my method doesn't work.

Wont continue to run after prime and start


often the last ounce of gas in the tank has some crud in it. Get a can of carbeurator cleaner spray. Remove the air filter and squirt three short bursts of the cleaner spray into the air port and then start it. Keep giving it short bursts of carb. cleaner until it runs smoothly again.

I have a troy built self propelled mower, it ran great last season, now it will not stay running. I checked to see if it was getting fuel and it is. I primed it and it acts like it is going to run and then...


The jets in carbs are really small and clog easily. If you stored your mower with gas in it start by replacing the gas. Remove the air filter and prime the carb. Start the engine and place your fingers over the air intake on the carb. This will cause the engine to stall as it will be starved for air. It will also create a powerful suction on the jets and possibly dislodge a blockage. Prime the engine again and start. If does not continue to run, repeat the steps again. If after 3-4 tries your engine wont run you will have to remove the carb and clean the jets manually. The reason your engine runs for a short time is because it is burning the fuel that you put in there by priming it. After that the fuel comes through the jets in the carb and if these jets are clogged the engine will die.
