Hello friends (can I call you friends?)
Yes, that is appropriate! :-)

I took out the sparkplug and some other screw that let me see into the gears.
the part about seeing the gears confuses me. How big was this screw? Many bikes have a small screw on the clutch cover case that oil will flow out of when the level is appropriate but I would not expect you to be able to see anything through this tiny hole.

When I tipped my bike on its side a whole bunch of oil spilled out and now the kick start is loose again.
Where did the oil spill out of, the small screw hole?
I suspect that the oil spill was not related, if you remove the screw and tip the bike oil should come out.

With the sparkplug out, it seems to work fine. shoots up access gas and the sound is just as I remember.
You shouldn't have "excess" gas.

With the sparkplug (a brand new one too) in the bike nearly reverts back to its old ways. kickstart now seems slightly jammed.
After you earlier post I had assumed that the engine seized. After this post I am suspecting that the carburetor is flowing so much gas that it has actually hydrolocked the engine.
Although it shouldn't happen and won't if all the vent tubes are routed properly and not plugged it is possible for a carburetor to allow raw gas to flow into the engine. I have seen people get concerned about the gas flowing out a vent tube and either plug it or route it up higher, which fixes a "symptom" but causes a much worse problem.
If the float valve fails to shut the flow of gas off the gas will flow somewhere. If it can't flow out the overflow/vent lines then it will flow into the engine. Note: I am assuming this is a two stroke. If you end up getting enough raw gas into the bottom end it can flow into the cylinder. A tiny amount raises the compression, a bit more and the cylinder is "hydrolocked" because there isn't room for the piston to come up.
Removing the spark plug will remove the hydrolock and allow the engine to turn over. If the bottom end is full of gas then I would expect to see it spray out the sparkplug hole when you kick it over. Put the plug back and in a few kicks it could hydrolock again.
If this is the case then the first thing you need to do is figure out what is going on with the carburetor. There are at least two problems: A stuck float and a clogged or improperly routed vent line. Fix these two problems first.
Now you have to deal with all the gas in the bottom end. You are taking the carburetor off anyway so go ahead and remove the reeds. Inspect them as it is possible that the bottom end hydrolocked as well and blew the reeds out.
Like whenfoxforksruled said, turn the bike upside down to get the gas to run out of the bottom end. Take the tank off, have the carb and reed plate off, spark plug out. Put the transmission into gear and spin the rear wheel to turn the engine over. After the gas has finished spraying/running out let the bike sit this way for an hour or so.
A word of caution: If this theory is correct you are going to dump a fair amount of gas out. Do this outside, well away from the water heater and other forms of flame!
