9 months usually will not be enough for the gas to go bad if it was sitting in a garage out of direct heat and weather. You can also tell if the gas has turned bad by the smell - you indicated it seemed ok - how did it smell? Since it is at half tank I would think it is low risk to fill the rest of the tank with fresh gas and start it. Max I would do based on your comments is just do a hand pump drain (there are plastic pumps available for less than $20) then fill it with fresh gas and get going.

Any advice would be much appreciated. Thanks.
