Is it even possible? Conversion question!

[zeek]

I have an old, like 1974 Sears 200 Watt generator that runs off of a Tecumseh engine, gasoline obviously.  How would I go about converting it to run on propane?  Does the old age matter?  I have read a good bit on storing gasoline and frankly it seems like too much of a pain, especially when I a 500 Lb propane thank that is hooked up to an empty trailer on the farm..why store gas?  Maybe I should just buy a propane genset?  Opinions?
Thanks

You can, Google is your friend.  But a new genset would be simpler and longer lasting.  Propane is dry and hard on valves and valve seats.

Conversion is possible and usually pretty simple. You may or may not be able to find a bolt on kit. If not, then it's usually just drilling and tapping a certain location on the carb for a gas fitting. You might want to do some research on fuel consumption for propane powered generators...they will empty a 500 gallon tank much more quickly than you might expect.

Engines last longer when run on propane vs gasoline because it is a cleaner fuel. The downside is that propane does not contain as much energy as gasoline, and that you will lose approximately 25-30% of the power output of the converted generator as a result.

With the age of that unit, is it a 4 stroke?  Oil may be the issue.
