I need a primer bulb for an earthquake cultivator.

Is there a primer bulb that you need to prime? is there a choke that you can fully close proir to attempting to start.try holding full choke and throttle on initial cold engine start.if none of these help then a weak diaphram fuel pump may be the issue

air breather pipe on side of engine blocked, or inlet valve stuck open,

The fuel line goes:

1. From the filter in the tank to the carb, usually the bottom most connector.
2. From the carb to the Primer. The tube in the center of the primer bulb.
3. From the primer, outer tube to the fuel tank.

Carburetor [A200774] for Lawn Equipment ' eReplacement Parts might have it but be where they have discontinued most carburetor parts good luck

hello l, how to change primmer bulb,,remove the two fuel lines making note which line came off where,use needle nose pliers to push the two ears down and pull bulb out,make note on where the long and short stem was at,go to the mower shop and get a new bulb and install,put lines back on, done start engine,,hope this helps,,

The primer pulls fuel through the carbruetor
So take your return line from the carb. and hook it to the inlet side of the primer and the other side
of the primer bulb transtions into the fuel tank.
You know when you have hooked it up right when you press the primer it fills with fuel and dumps back into the tank.
