Priming echo BP251 liaf blower


Hi Norman:
I'd check the routing of the fuel lines.
Tank to carb (this is the line with the filter on it)
carb to bulb (suction side)
bulb to tank (return line)
If the connections appear correct but it does not pull gas, check the filter to make sure it is clean, and you can try reversing the connections on the bulb.
Hope this helps.

Primer bulb collapsed


Slightly unscrew the gas cap and see it the problem goes away.
Many times the Gas tank Vent clogs and this will cause the engine to create a vacuum in the gas tank until the engine can't draw in the gas .

I can start my 4.75 HP Briggs & Stratton Lawnmower but it dies after a few minutes. I replaced the armature but the same thing happens. I can keep it running if I press the prime bulb a couple of times...


Try replacing the float and needle. The float (floats) and pulls the needle up to let gas through to the carb. It will stay running as long as you press the prime bulb because this sends gas straight to the carb without going through the gas bowl. It's best to remove the carb and clean it then replace the float and needle

I have a push mower with a briggs and stratton 3.5 hp classic. The old primer bulb developed a crack in it so gas would leak out when priming but it would start and run until no more gas would go into carb...


Take the fuel bowl off the carb and check the metering valve to make sure it opens and closes sounds like its closed not allowing fuel through the carb. Its a quick easy and very cheap fix....

Honda FG100 tiller will not prime, filter replaced


Well if the unit has fuel than it should prime unless the primer bulb is damaged and unable to force air/gas through the line. This is definetly a fuel issue, I would remove both the line from the tank to the carb and carb to engine and clean them thoroughly.

When you press the bulb the carb should shoot gas from the unit when disconnected. If this isn't happening your clog is here. If it does eject gasoline than your clog is the clear line which sometimes collects sediment if the gas is poluted.

Engine starts when I hand prime it,but not when I use prime bulb.


There are two screws on the carb. 1 is Lo rpm air/fuel ratio and the other is hi rpm. Try adjusting the lo rpm screw counter-clockwize a 1/2 turn at first, more if needed. After each adjustment try to start. The other thing you could check is if the float is sticking in the bottom of the carb. which shuts off gas flow if full. There is a screw on the bottom of the carb to drain that float. You can try that also! Good luck man!
