mower engine hunting?

I agree with plug and inline filter (no need) but to give the carb a damn good clean may rectify problem.if problem persists then try diaphram.

this is probably the most common fault i fix on a daily basis if like pleasent said it has a metal tank then i would put a tenner on him giving good advice
the only thing i would add is to clean the tank and carb while you have it to bits

errrr... I wouldn't say the earlier answer was a lot easier- certainly a lot more expensive fitting an unnecessary plug and in-line fuel filter. Especially no mention was made about fitting a diaphragm kit whilst you've got the carb stripped down.

Like I said- most of what was suggested is a waste of time and money.

Save yourself a lot of time and money and ignore most of what killerdanny has just stated.

My guess is that you have a briggs and stratton engine with the fuel tak on the right of the engine (standing behind mower) with the carb and air filter on top.

you have, then all you need is a carb diaphragm kit pt no 795083 for a couple of quid from any dealer.

Simply remove the air cleaner and the two bolts that hold the tank/carb assy o the engine and remove fcompletely. Stick it on a bench and remove the 5 ross headed screws that hold the carb to the tank. Lift the carb from the tank and remove the existing diaphragm and gasket sandwiched between the bottom of the carb and the surface of the tank. Lay the diaphragm on the tank flange first and then the gasket. Lower the carb back onto the new gasket/diaphragm and carefully replace the screws into the carb flange. Equally tighten the screws.

Re-fit the carb/tank assy and re-fit the air filter assy.

Re-start.

replace spark plug ,remove and clean air filter, if problem still persists remove carb ,strip and clean,may have blockage in main jet,.fit inline fuel filter to stop further blockages.
