I am looking to make a wind driven generator. My thoughts are that if I buy a gas driven generator it has all the converters and such so I can just plug in and go.I can adapt it to wind. I can buy a gas generator without a motor. Or does the gas driven one have to much torque compared to a wind generator?
I hope this makes some sense.

The first point is that a wind generator only produces electricity when the wind blows. So some means of storage such as batteries would be required.
Buy a fan it is cheaper, but you need a motor that turns very easily.
A fan blows air and it can be turned by air to generate electricity. It also has the windmill blades attached. It will generate AC power not DC power.
Without the motor the gas generator will NOT generate any electricity, you need the electric motor to act as a generator. There might be decent electric conversion equipment on the gas generator. You need a way to prevent the electricity from flowing back into your fan to turn it into a motor instead of a fan.
buy yourself an automobile alternator from the junk yard and you have a generator that can produce power no matter what makes it turn, either gas of wind. you control the field current of the alternator to extract as much power as the wind source is able to supply. if the load is too high and the windmill slows down you reduce the field current and thus the power output of the generator and the windmill keeps rotating at its optimal speed to extract as much power as it can from the wind.
No, it makes no sense.
That gas driven generator has to be speed controlled at the motor to
generate the proper voltage and frequency.
Your windmill can’t do that without some rather complex sensors and variable
pitch vanes which are well beyond your ‘do it yourself’ territory.
Your best choice for a ‘home project’ is an automotive alternator,/voltage regulator,
batteries, and an inverter.
All shelf hardware designed to work in a fairly wide speed range, and all the hard
engineering has already been done, tested, and reliable.
Wind generators have a great deal of gearing because the blades of a wind generator move slowly and provide considerable torque from long blades (and can’t move faster because the turbulence from one blade messes up the next one) while a generator is more efficient the faster it turns to rotate the fields past each other faster. There can be only limited speed regulation of a wind generator and that comes from an expensive hub to rotate the blades, so smaller ones regulate the voltage output and turn the blade unit edgewise to the wind to stop it.
Motor driven generators do (part of) their regulation by controlling the speed of the gas motor. So you would be buying a unit that would be missing the part that gets regulated and get control circuitry that has nothing to connect to.
