Rv Onan Generators

My Generator turns over but won't start. What should I do?
I got the Onan Microlite 4000 series generator with an RV, and it has not been started for some time. I've replaced the spark plug and tested that it has a spark. Also I inspected the carburetor (it was clean) and drained it of old gas. I used fresh fuel and drained the lines of tho old fuel. The fuel pump is working well. I also gave it an oil change and filled it properly. Anything else I can do?
Before you attempt to run this, get some wd40 or PB blaster (my fav) spray it down the spark plug hole and turn it over to lube and break up any rust formations that may have occurred . Replace the plug, spray the ether starting fluid down the carb and it should start.
I leave my lawn mower outside all year long and the in spring the ether starting fluid works beautifully. It stumbles for a minute or two then smooths out.
If it has compression, spark and fuel it should turn over. I surmise there may be improper atomization from the carb due to varnish forming in the old gas.
Try some starting fluid down the carb throat. If it turns over the carb needs cleaning out. IF it doesnt its possible you may have spark but insufficinet compression. It could be the rings have stuck in the piston grooves and caused poor compression.
