How to replace carb. Primer?

SOURCE: Toro Lawn Mower Won't Start

this is a very common problem with these toro mowers. the needle valve in the bowl of the carb. is plugged up with dirt or varnish from the fuel. just under the primer bulb there is the carb bowl. it has a nut under it that holds it on remove the bowl and make sure fuel flows constantly while the bowl is off. push up on the float to stop the gas flow. this could be messy and dangerous. careful with the gas. its flammable. best solution is to remove the carb and soak it overnight in a parts cleaner like gunk. caution small parts inside. this happins every year on mine no matter what i do. seems like the orifice is so small it clogs easily. good luck

Without the mdl # I can't be for sure but I am 99% positive it is unleaded. Same as your car if you are in the US.

Carb. float must be stuck open. First if you have no fuel in the tank it must all be in the crankcase.Drain the oil and refill and also check the carb as the float has to be sticking open. Hope this will help you. Donnyb60

Your carburetor is definately dirty or it needs new gaskets, screen, and needle valve( carb. kit). Is this something that you think you might want to attempt? It really isn't that difficult. Can be done in about an hour. If so, let me know and I can give you a few tips.

Had this problem after I inherited the same mower. Take the carb off and remove the "bowl" using the bolt at the bottom. You will see a plastic float and a needle valve. Remove the float by puling the the pin and clean the needle vale and ensure it moves freely. Also clean the "jet" that holds the float washer to the carb assembly. Also clean the bolt that hold the bowl on.
