 Greetings, I have found and git running a 9A34-1A Homelite generator. 

 Here are the numbers:
Model 9A34-1A
Serial number: 40087049
Watts: 3400
Single phase
Volts 120Amps 28.2

 Any help finding the date of manufacture would be great.

Welcome to HOH! Based on that serial number, I'd say it was built on January 8th of 1974.

 Thank you for deciphering that number. I had no idea how to come up with that.
