Question about Garden
There may be a malfunction in the check valves in the primer base assembly. Before attempting to get a new assembly, take the retaining screws at the bulb off, remove the bulb and spray the assembly liberally with WD-40 or an equivalent light lubricant. Sometimes this will free the check valves as they only let fuel flow one way and there are 2 of them in the primer base.
Do not use strong solvents, do not ever soak, and never use high PSI compressed air on these carbs. Sometimes, when the check valves in the primer base go bad, the carb floods and the reason is unclear. Zama doesn't list this as a reason for their carbs flooding, but they can. You may wish to view a parts breakdown list for your specific carb. You will need to know the type (stamped in side of carb body) and the model (stenciled in side of carb body). It will be something like a C1U type and a W-18A mode...thus its a C1U-W18A Zama carb. Here is a link to get you started.
Yours will be listed under Poulan/Weedeater
