Hi., I just bought a brand new petrol mower this weekend. I measured
and filled the oil and petrol correctly. Its a 4 stroke engine

It starts without too much difficulty (though not as easy as Id
expected).
After mowing for maybe 30 seconds, the motor rapidly fades and then
stops.
At this point the starting cord is very tough to pull, and I generally
have to leave it for a while before I can start it as easily as before.


What make of mower is it, ive heard that the Chinese manufactured engine in
the Challenge/Power devil type mower is extremely unreliable.

You did put the oil in the crankcase and not mixed with the petrol ?
