Primer bulb on Yardboss blower will not **** fuel from tank. Blower will run if primed manually.


remove your carb and clean it and replace diaphram's and needle , they tend to swell up from ethanol that is used in the gas now a days, and the diaphrams turn stiff and won't pump fuel. then put fresh gas in when you are done and also replace fuel lines and filter too., probably primer to because once it is hit with carb clean it just crumbles, good luck

Walbro WT891 carb on a Craftsman chainsaw. Carb is brand new, all fuel lines and fule filter replaced. I prime the carb with the little plunger, chainsaw starts up and runs out of fuel within 30 seconds....


Who connected these hoses? the normal routing for a machine with a primer is like this, the fuel hose from the tank with the filter on the end goes to the carb fuel inlet nozzel ( not to the primer ) nearest to the pump cover ( cover on carb held with one screw ) the pipe from the metering side of the carb connects to the shorter nozzel on the primer bulb ( suction side ), the longer nozzel on the primer ( pressure side ) connects to the pipe going back to the tank, just remember the primer pulls fuel from the carb,into the bulb, and pushes it back into the tank, it is not actually a primer it is a purge. because it is connected this way it is impossible to flood the engine no matter how many times the bulb is pressed.
Let me know if it starts and runs.

Replaced all lines (2) plus bulb and still can't prime blower.. if I put gas in spark plug hole runs fine.. even tried leaving off the filter in tank. thanks


I am under the assumption the primer bulb is atop the carburetor. There are check valves under the bulb in the primer base assembly of these carbs. Sometimes, the valves stick and sometimes they go bad completely. There are very small and for all practical purposes unserviceable, however...you can try this...pull the fuel lines off of the carb and spray WD-40 into the brass inlet and outlet. Remove the primer bulb again and liberally spray some WD onto the top of the primer base assembly...this being done in hopes of freeing up a sticky check valve. If you have extra or old fuel lines, hook them to the carb...inject WD-40 and work the bulb to attempt to move the lubricant back and forth out of the carb. Sometimes this works, sometimes not..if valves are bad. There are replaceable parts and kits for the primer base available on the manufacturers websites. The primer bulb does not have to be completely full of fuel to allow the engine to run, but the base assembly can cause problems in fuel flow to and from the carb and even mimic a flooding condition. Don't use carb cleaner and dont soak the carb in any,. Try this and post back if needed.

Replaced gas tank and primer bulb on my Poulan Leafblower FL1500 and it appears I'm not getting gas into the carb. Any ideas as to what my be the cause?


I assume the new tank came with new fuel lines and filter in it.
First be sure you have all the lines hooked up correctly. There should be a main line from the tank ( has the fuel line on the end of it in the tank) to the fuel pump side of the carb. Then there should be a line leaving the metering side of the carb to the primer bulb then from the primer bulb returning to the tank. When you press the primer bulb you should see it **** the fuel into the carb then from the carb into the primer bulb then back into the tank.
If the fuel lines are all hooked up correctly then you should rebuild the carb.

No gas when you prime it


1) Check fuel lines from tank for cracks, fuel filter in tank, primer bulb for cracks

2)Remove Carburetor
replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside

PRIMER BULB WONT PRIME


I would recheck the carburetor to make sure you put the diaphragms next to the carburetor and not the gaskets.
Please if it is not priming you may have the fuel lines hooked up wrong. Also check the fuel cap to make sure the vent assembly is there. If the tank is not venting, the tank will get a vacuum in it not allowing fuel to flow.

Good Day.

Primer bulb on weedeater won't prime


when you prime the bulb it sucks gas from the tank with the small tube, any excess gassed pumped will be fed back to the carb via the big tube leading to the tank. If you prime it and the bulb stays pushed down, then you have a clog or kink. To fix , pull the small tube out of the tank through the fill hole. Pull off the filter on the end and put the tube back in the tank. If it primes, your fuel filter was clogged. If it still wont prime check the hose going to the carb and make sure isnt clogged or kinked.(take of carb and blow in it). If that doesnt fix it take off the bulb from the carb with two screws. The bulb assembly will come off too(rectange metal thing) Take off the two black gaskets, be carefull with them. Take off hoses from carb and bulb asembly. Blow carb cleaner in all holes and over surface. Put back together.
If the carb wont prime and the bulb isnt staying depressed. then you might have a bad bulb or carb gaskets. Make sure hoses are not cracked, cloged, or pinched.

Can't start my Poulan Woodshark Model 1950


Replace the fuel filter. Sounds like you have the primer lines hooked up backwards.
