good spot 
there a chance they might have put the connections on the wrong terminals
this sounds like the right one then

It would be worth getting a wiring diagram for that motor just in case, I bought 2 identical used compressors and one of them the motor didn’t work and had been messed about with, when I checked the wiring against the one that was working they were wired differently, copied the wiring from the other one and it ran fine with the belt off but would only run for about 20 seconds with the belt on then it would slow down, stall and I could hear the motor buzzing, pulled the plug before tripping the CB or seeing magic smoke, couldn’t see anything wrong with it when I stripped it so bought a new motor, Machine Mart was the cheapest price I could get for a new 3hp motor.good spot

Hopefully you won’t need to go down that route, I thought the problem with mine was the start cap a new one didn’t help though.

If you mean on the capacitor it doesn’t make any difference which way you connect it.
With the pressure washer motors I work with that capacitor would have been replaced long before the capacitance had dropped that low.

looking online a knackard capactor can damage the motor make it run hot possably melt the windings
will have to see when i replace the new one ordered if it makes any differance ?
is it worth changing the oil ? and what type ?

update a new capactor seams to have worked wonders starts runs as should or at least for a bit of testing that ive done
set it up to 8 bar (same as my older one) seasms to cut back in at around 3.5 bar i think seams a bit low to me im assuming that can be changed ?

This is the switch I've just seen there is a 2nd screw I'm assuming this is the start screw
The unit does loose quite a bit of pressure over night and has lost about a 1.5 bar over couple days possably a bit less and there's not any thing even plugged in to it

screw top right is the pressure stut off
the screw head to the left id guess is the start one ?

Quite possibly,
So with the compressor flat, I'd suggest turning it 1 complete turn (mark the screw head with a bit of RED paint to indicate a starting point) then run the comp and see how it affects the stop start.
Its possible the two adjustments may interact... ( that is the pressure at which it starts and stops, you may need to adjust the Stopping setting..)

ah got you might have known it might not be as simple as ones the stop pressure and ones the restart
