I Finally got it, I tried everything. I tried, heating it, freezing it (lol), sanding it, lubing it and finally i just cut the damn thing off with a flex... And the blade came off, and for some odd reason that was left of the screw came off easily, I actually took it off with my hands, i guess the top part was the problem and the vibrations of the flex made it unscrew..
Anyway, now, what choices do i have? What can i do with this working engine?
I really want a go-kart but it has a vertical engine, and i've been looking everywhere for a used horizontal one arround here and I can't find one. I've heard of a few things, either, remaking the oil injector things and turning it over or buying some expensive gearbox.. I've also heard of some ways that seem to be pretty... long shot...
1. Using a V-Belt and rotating it
2. Overfilling it with oil so it still gets lubrified.
Anything else? Do these sound tryable?
Also, if it's really hopeless, what else could i do with this engine? Any ideas?

There are several topics already here that cover go-karts with vertical shaft engines...A search should turn up all the info.

Yea, interesting reading this topic, i had 2 lawnmowers with the exact same problem. No matter how dam hard i tried to get the nut off, it would give up.
Advice: Do not, i repeat do not try and get a rusty nut off a mowers axle thread, it's a waste of time. Though it also depends on how long the nut has been rusty for.
I replied to this message because i didn't have anything ells to do.

As for running the engine sideways, DON'T DO IT. The lubrication system will not function if it is turned over. If you want to run it sideways, you will need to modify the carb/fuel tank, and install the oil dipper from the horizonal version of the same engine to provide lubrication to the valves and cylinder.
I dunno about that... It just so happens that I had the crank case cover half off a 3.5hp briggs and stratton engine, and it doesn't even use a similar lubrication system than the horizontal shaft briggs uses (pulled one of those apart too) while the horizintal simply has a splasher that dips into the oil every rotation, the vertical had a wheel, driven by the cam gears, with multiple "blades" that dipped into the oil.. the whole mechanism was also attached to the cam shaft, so it could rotate if the engine was tipped... (well, all that is to the best of my recollection)

Which is why I have said you need to replace the cam driven slinger with the dipper. The cam driven slinger doesn't rotate enough to catch oil when the engine is rotated. I have done this to several engines, and have taken apart hundreds of little B+S engines, so trust me on this.

hey, I trust you on it.... I guess... why couldn't you put more oil in it to raise the level? speaking of oil levels, what happens if you over fill the oil in a vertical shaft B&S engine? cos, the one I was working on, had a dip stick.... with "do not over fill" written on it, and ofcourse, I over filled it. :p

You'd have to probably put in 3-4 lires of oil to make the slinger work in a horizontal application. Even then, it will be pushing the oil the wrong way, and the massively overfilled crankcase will lead to other problems....
....which is the 2nd part of the question. Overfilling can cause many things. Oil will by pass the piston rings and get burned off. The major problem is that the crankshaft tends to turn oil into a froth of air bubbles. This froth has almost no lubricating properties. Also, the exrtra oil is a major drag on the crankshaft and causes power loss.
