could be the coil pack also if it isn't firing on all cylinders. Does it sound like a tractor? and has very little power at all?
From past experience, when the engine sounds like a 2 stroke and the power is down its coil pack issues.
Saying that, not sure what the shaking gearbox could be. wouldn't be related to a cylinder not firing.
so if i get a service and its on a lot less than that do i not need new spark plugs?On a 1*2 every 72k
suppose you could remove them and see if there is anything out of place. would be easier to change the coil pack first though.
