I think you might have figured out the problem and fixed it by now. From my limited knowledge it seems to be a overflow issue. Get the carburettor checked maybe. And do post about what the issue was and how it was fixed if you already did!

Hi, sorry for not replying. Yes i finally got the problem fixed, it seems it was a problem with the float in the carburetor. First it worked as some fuel was in the carburetor but after that it had problems as it seems the flowt was wrong. A friend took apart the carburetor and cleaned it, was dirty inside, they also replaced the seals, nozzles and jets inside with new ones, i ordered a full kit online for about 15 pounds. Now it is running much better. Still sometimes stops if left idle for a while but i think need to adjust the air and fuel screws a bit more.

Good to know you got the problem properly diagnosed and got it fixed. Usually for float problems , wherein engine flooding happens like in your case, it is adviceable to change float, the Pin to close the petrol flow once level is attained , along with the Pin seat. Usually the seat fixed in the carburetor is missed leading to recurring problem... The Air screw adjustment is 1 and half turns Anti Clockwise, AFTER GENTLY turning it Clockwise till it stops. If you are a person who likes instant acceleration then 1 and a quarter turn will do. One or less turns on Std., bore will lead to sputtering and wastage of fuel, and bike actually becomes sluggish.
