It looks similar to a PUMA PK-5020VP and it is not 4HP, 4HP at 115 volts iwould draw close to 30 amps! the plug shown on your compressor at best can handle 20 amps for a short time. An electric motor running at 115 volts and 13 amps can make about 1.5 HP actual output, labeled as drawing 12.5 full load amps. Hype "Marketing" or "fantasy" HP descriptions are quite a common trick for compressor sellers. I don't see a pulley on the motor, do you need help to figure one out? Compressor head is a cheap Chinese one similar to Replacement 5 HP Twin 2 Cylinder Air Pump for Air Compressor Compresser Unit for sale online | eBay

Calibama65,

The one listed below recommends up to a 3HP motor but you can use your motor with the correct size drive pulley. The pump pulley vs the drive pulley will determine the speed and CFM output.
Actually this one looks closer :
