Help on an old Chrystler Outboard

I was recently given an 18 foot Chrystler Cathedral boat with a 120 hp outboard motor. The guy said it ran 2 years ago when he stored it but it won't run now and I am at a loss. I have changed the plugs, checked for spark on all 4 plugs, made sure the carburator is getting fuel, checked the compression (with seems to be good), and made sure alll the wiring is in tacked. I have tried spraying starting fluid into the intake and straight into the cylinders but its not firing. The starter is still strong and it turns over fine but again it won't fire. If anyone has any knowledge about older Chrystlers or a suggestion of what could possibly be wrong the help would be much appreciated.

Thanks

More info:year ?model? You tested spark,was there spark?What's the compression? Water in the fuel,old fuel.
When you spray starting fluid does it cough or fire or anything?
