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. Some resistance to my finger and a slight "sucky" noise, but no fuel coming through.
Thinking I must have dragged some muck into the carb and blocked it when the petrol ran out, I've taken everything apart this morning and given it a good clean. However the primer bulb still isn't working.
The inside of the carb is nice & clean now. The primer bulb is fairly new and in good condition.
Does anyone know what might have happened & how I might go about fixing it?
I did notice when inspecting that the gasket next to the diaphragm (between fuel tank and carb) had a small tear in it. Could this be the source of the problem? (the gasket and diaphragm kits are very cheap so I might replace them anyway just as a bit of regular maintenance)
Thank you,
Alan.
