Way back, the landlord had 2 2000series Cubs ( runs 5 now )
One had a hood & one did not
The one with the hood would run 1/2 hour to an hour then peter out till it got cold then it would be fine for another 1/2 to 1 hour.
The one with no hood would run all day so we naturally looked at overheating .
A full year latter I went to change the fuel filter as I could see it was dirty
We had been through all that "looks empty rubbish "
Well the mower was full of petrol and pointing down hill so I clamped the fuel line then changed the filter
And sure enough when the clap came off. no fuel came out .
So next thought was collapsed fuel line so I blew back through it then nearly drowned in the gushing fuel
Mower ran fine for its usual time & every time it stopped we blew back and away it went
Now it is a big job to get that tank out, but we did and then strained the fuel
We ended up with a golf ball sized clump of old TRANSPARENT grass clippings .
From that day on a 2 liter fuel tank of a 11 Hp Tecumseh became a std diagnostic tool , kept in the service van.
Around 1/4 of the runs fine then stops jobs end up being trash / water in the fuel tank
