drain your tank and flush with some gas. you should also remove the bowl from the carb. and drain it as well. Then clean out carb. with carb. cleaner. you may need to get a new gasket for the bowl as well.
Remove the carb and take the bowl off the bottom. Remove the jets and soak in carb cleaner. Make sure you can see daylight through them.
remove the the bowl on the carb and clean with carb cleaner, be sure to clean the main jet. and the small holes in the bolt that holds the bowl on, if these are plugged the mower will start but not stay running
get a can of Carb Clean and spray outside of carb first, then remove all jets,and the bowl and remove the float and needle and seat,and spray thru all ports.blow out with low pressure air hose and put back together,make sure the needle is free and goes up anmd down with the float before asembly.
Get a can of carb cleaner remove carb. Unscrew throdle cable cap, Needle, Slide. Remove 4 screws from bottem of bowl remove bowl spray with carb cleaner spray in to jet you can remove if you like dont poke anything in to jet they are made of a soft metal. Reverse process to put together
Sounds like the main jet inside the bowl of your carb may be plugged, there is no adjustment on that choke of that bike it is either full open or half open. take the carb off the bike and clean the carb fully outside and remove the bowl and clean the passage ways of the jet or order new one, reattach and try it again.
A can of any brand carb cleaner, one with a tube to direct the spray where you want. 9 times out of 10 I can remove the bowl and shhot some carb cleaner up the jet from underneath and solve the issue right away.
Sounds like dirt/crud in the carb. You need to remove, disassemble, clean and reassemble the carb.
take off the carb. on the botoom of the carb is a bowl take screwsa out and the big jet in the center is the main jet. remove with a flathead screwdriver
There should be a small screw in the bottom of the bowl on the side of a little spig (hose ) connection. You push a small hose on to it then put other end in a container and open the screw ( the screw does not need to be totally removed it should start draining after a couple of turns) and if that does not work you will have to take carb. off and remove the bowl. If you are going that far then you might as well clean the carb well it is out. Hope this helps.
if its the venturi in a carburettor than yea jus buy some carb cleaner get somone to hold the revs up to bout 2-3,500rpm and spray the carb cleaner directly into the carb or could always remove the carb and clean it thoroughly [if ya know wat your at]
The carb bowl drain nut is located on the bottom of the carb.
