Yamaha 6300 will produce 45.8 continuous amps using the 240 volt position , I use converter plug to a 50 amp 4 prong plug You did not specify the amps of your compressor but
25 amps on each 120 volt leg, equals to 50 amp 240 and I guarantee your compressor does not use that much. The 6300 weighs 200lbs and can be bought at National Supply on the internet delivered the cheapest of all suppliers 1-877-316-3954

I have same generator. Will not start. Good spark, good fuel, good carb. Compression is 60 psi cold. Is this good? Bad? I can't find anything on what compression should be.

If you have not properly shut down the unit after use you will have likely had fuel remaining in the carburetor. The fuel will have evaporated while the unit was stored leaving residue behind. This residue will plug and interfere with the fuel passages and metering orifices of the carburetor. The residue reduces the fuel flow through the carburetor. Applying the choke compensates for the reduced fuel flow returning the fuel air mixture to a burnable ratio. If the unit runs with the choke on it is likely the carburetor is dirty. Be running the engine the carburetor will possibly clean itself. Make sure you remove any old fuel from the machine and replace with fresh. Allow the unit to run for an extended length of time attempting to return the choke to the run position. If you are able to return the choke to the run position you are on the way of solving this problem. You may need to run it additional time to completely purge the residue.

Additives are available to clean the carburetor and as a last resort if running with fresh fuel doesn't' return the motor to normal you may try it. For best results after mixing and running with the additives leave the unit overnight which may help to remove the remaining residue.

The shelf life of gas containing ethanol is about 30 days. In the future it is best to run the unit dry leaving ot fuel in the carburetor.

All else fails you will need to have the unit serviced by a small engine service center.
