Customer brought in a local push mower fitted with this 140cc engine complaining it had a tapping noise.
Previously it had been in for blades touching the baseplate which was beaten out.
Thought it was the same problem repeating but the blades are fine
When rotating the engine by hand I get a definate click from the ACR unit when the valve closes
Is this normal ?
I don't remember it doing this when it was serviced 3 years ago .
Would I be correct in diagnosing a deceased cam ?
Do these engines suffer abnormal cam problems ?
it is a 2016 build on an 18" mower with swing back blades & customer has a small domestic property about 1/6th acre with a big house so not much lawn.
Last year was the first set of blades & generally swing backs get replaced every 2 to 3 years so it has not done much work .
