There are a few things that you can do yourself to try to get the car to start.
1. Make sure that the oil level in the engine is full.
2. Have a good battery (sounds like you've done this)
3. Install new spark plugs. Generally speaking, most plugs are 'generically' gapped and would be close enough to allow a Kaiser engine to at least start. Champion J8C plugs would fit the bill.
4. Buy yourself a can of Gumout carburetor cleaner. It's in an aerosol can and will accomplish two things for you...it'll clean the carb throat when sprayed in and it will act as a starting fluid. Don't use ether as a backfire can cause a blown piston. I have seen it happen and have the exploded piston to prove it.
Spray about a 2 second burst of the Gumout into the carb throat and then try to start the engine. If it doesn't fire, pull off the #1 (first) spark plug wire, insert a spare spark plug into the end and lay it on the top of the engine. Try again to start the engine and observe if there is a spark at the gap end of the plug. If so, your electrics are OK. If not, the ignition system will need attention.
I sure hope you find someone to help get the car back on the road!
