Hi Phil, it is a new motor.
I will try it with a larger capacitor added as a starting cap and see how that goes.
If that works then I will get an electronic starting switch for it.
For now it is working with the air gun spinning it up a bit then hitting the starter.
Once I start it it runs great.
The capacitor on it at the moment is 50 uf , I think I have a much larger motor start cap in the shed so will dig it out and see how that goes. I know it only needs to be in for a second or two, so will just experiment and see.
I have a short 15amp lead that I am using for it, so no long leads. I have seen many air compressors killed by long leads.
Cheers
Pete
