What other options do I have?
You could always hand nail.
As for running a compressor on a generator its possible. You could also rent, beg, borrow or steal a gas powered compressor.
As for starting amp draw versus running amp draw - I'm not sure. My 15A compressor trips 15A breakers on startup 90% of the time. It has one or twice tripped a 20A breaker!
I would suspect an 8a compressor will be fine on that generator.
I know for a fact that this one works great on 15A circuts and is very quiet.http://astore.amazon.com/handyguys-2...563199-0409762
