Primer Bulb Problems - Lawn Mower Forum

Mar 25, 2018  Hello forum, I'm relying on a very old lawnmower at the moment which is powered by a Briggs Stratton Classic 3.5HP petrol (whoops - gasoline for any readers from the USA) engine. It was working ok until a few days ago when I accidentally let the engine run with an empty tank. The engine cut out of course. When I refilled the tank later on, I couldn't get the primer bulb to work.

lawnmower primer bulb,sucking in and stopping? - Google

Jul 22, 2012  A lawnmower problem most definitely doesn't belong here. However, my guess, based on the information you have supplied is the vent on the tank is plugged. Or the line between the tank and the bulb is somewhat plugged. Either will cause the engine running and drawing fuel to create enough suction to collapse the primer bulb.
