Thank you petak, for this very detailed info and how to.
I have managed to adjust it, and i assembled everything back.
Went for a test drive with a friend, and with the adventure we had, i forgot to check if it works as it should.
Didn't take it for a spin after since i'm a bit scared if it now :P
Long story short, it stalled again, hiccups, not turning on, turned on but no power.. It's dirt and rust mud in the reservoir and tubes and filter. So, we figured we'd feed fuel directly and decided to pump it out in a jar. Very stupid move. He held the pipe that runs from the fuel pump directed in the jar, while i was cranking it so the pump would indeed pump the fuel out, and all of a sudden, a giant fireball or should i say, fire cloud, covered the engine and my friend. He didn't catch on fire but the engine did, and fuel pipes too aswell as grass around us. It was pitch black, so imagine that. Luckily, i managed to put the fire out by wiping the fuel off with my hands and covering the pipe so it wouldn't leak more fuel out.
All in all, a very stupid idea, very stupid. It would've worked, but the execution wasn't really bright.
