so should i just hook the fuel line into a can of gas for now?
Yes, the lines and tank cannot be trusted.
and I cannot give you any better advice than Dksix. I am a diesel/ATF man myself. Or you can use Kerosene.
In any event, his advice is perfect, especially the gentle free up. Turning it over easy before starting. Great advice all of it.
Get the carb working for real, accelerator pump and all.
Flush it with carb cleaner and penetrating oil or take it off and clean it out if you have to.
Check that the fuel pump works and fills the carb and the accelerator pump works.
What does the oil look like? Drain it and put cheap stuff in there for now. Too much chance of water and critters in there.
Crank it over on the starter and look for oil pressure. Use the ether and oil so you don't wash the rings and it has compression.
Keep medium revs (2000) when it starts and let it run a minute at that.
If it skips, you may want to slowly pour a couple glasses of water, then ATF down it as it revs to free rings and valves and carbon and rust.
Nothing I like better than a good revival!
