I have a Craftsman 5.5 hp lawnmower.

It is very hard to start lately.

I have replaced the carborator, about a year ago.

I replaced the sparkplug at the same time.


Once I get it running, the idle is up and down. If I hit a thick patch of grass, it will stall.

I don't see an idle or throttle adjustment.



Not sure what to do next.

The gas is about year old too, could this be it? I store it in a sealled can.


Thanks for any suggestion

How old is the mower?? Some of the newer models don't have a throttle.

Could very well be the gas....year old gas is not good at all.

If the engine is 'hunting' (idling up and down) the carb needs a good cleaning. Perhaps when you installed the new carb you did not connect the governor linkage....that could be the case for stalling on the patches of thick grass.

We need to know the year and model of your mower.

I'd say the governor is most likely the culprit.

Some plastic gas cans are permeable and allow gasoline to degrade, so gas can go bad even tightly sealed. Metal cans are not perneable so keep gas longer.

@SABL You nailed it, it was bad gas. I keep it stored in a shed, out of the elements. Never thought it would go bad after a year or so. Guess I will get a smaller can and make trips to the station.

Thanks for the support!

Glad to hear you found the problem.....

My mower sits for ~5 months in the winter. On first start-up in the Spring I can smell a difference in the exhaust from old fuel. I'm kinda pushing my luck by not using a fuel stabilizer......

*Mine's not pull start.....60" commercial Z-turn.
