The contactor is size 0, which according to code is good for 3hp on 230v. You should by rights be using a size 1.
You need a start capacitor if you want pushbutton start, this should be motor start grade, intermediate use, as opposed to the run caps, which should be continuous rated.
Others have used a crude way of starting by pony motor or rope pull start to get the rotor turning initially.
The P.B. start is more convenient.
