Not really.
Got a crusty old Rover 4-stroke that someone gave me a couple of years ago.
Had been sitting in a shed for about 6 years when I got it.
I took it to a local backyard lawnmower fixer bloke, and he replaced the primer bubble and a gasket.
Never missed a beat since.
Might take a photo of it later.
Also have a Stihl 45cc weedwacker on indefinite loan from my girlfriend's dad.
One of those sissy bent shaft ones.
Goes ok though.
Hardly ever need to mow here anyway as it hasn't rained for months.
Which is good.
