You may have to replace the carb.But before you do.Check the the fuel line.There is a small screen in the carb,it may be clogged.Inside the tank is a small cylindrical filter,make sure it is good.Break the fuel line at the in line filter,to make sure gas is getting to there,if it is the problem is in the carb.

SOURCE: murray mower starts with choke but dies

most likely your main jet in the carb is clogged, water in fuel, or a plugged fuel line, filter, or plugged in the tank where the fuel line connects. it is common to have a plug where the fuel line exits the fuel tank if there is a 90 degree turn in the fitting, debris may build up in the 90 degree area. check by replacing old fuel with new, then pull fuel line from carb and fuel should flow freely, look for a blocked fuel line if it does not flow. it it does flow, pinch off fuel line then remove the float bowl to drain remaining gas and give acess to the main jet. the main jet is located in the side or bottom of the lowest protruding area into the float bowl. run a thin wire like a guitar string thru the small jet hole to unplug, then squirt a little wd-40 thru jet hole to visually check flow. next, unpinch fuel line and fuel should flow from carb into float bowl area. then check to make sure the fuel stops flowing when the float is gently lifted to the top of its travel. if problem in this area, remove float pin, float, and needle valve and check for blockage in the needle valve seat. clean out with wd-40 and reassemble, add fresh gas and give it a try!

I have a 2003 xr 80 dirt bike. The spark plug is new there is gas and the oil is good and it wont start. Should i clean my carb?

yes, clean out the carb if you add gas directly to the carb intake, and it runs for a few seconds and shuts off, then you know you have a gas supply problem at the carburetor.

I accidently put two stroke gas in the fuel tank and ran it a few seconds, then it quit. Drained the fuel and added new fuel, but will only run a few seconds?

hi because you ran engine and it stopped/failed to restar although you renewed fuel which was 2 stroke ? the wrong fuel will be in carb's float chamber and probably ran engine eventually oiled plug may i suggest you clean plug then clean carb out remove main jet and idle and blow them clear so you can see thro them refit and fill f/chamber to 3/4 full then re assemble carb should start then

Your carburetor needs cleaned. Disassemble and spray with carb. cleaner. TIP: Use a Den Tek Brush, (used for cleaning between teeth),to clean small portals in carb. check the small screen in carb. for debris. Reassemble and start. If it still doesn't run properly, buy a carb. kit and replace the small screen, needle valve, gasket(s), and diaphram. this should definitely do it.

Poulan 6.75 Lawn mower will not start

Remove spark plug, clean and dry. Replace plug. Remove air filter. Spray WD-40 into carb opening; one second blast. Turn over engine, (pull handle). Engine should start briefly and run for 3 seconds.  If not, you are not getting spark to spark plug. If engine starts, you have a dirty carb and you can buy a rebuild kit from manufacture.
