The mechanic i took it to said he will pull of the carby, clean and reset the screws, floats and stuff.

Anyways the same mechanic said i replace the spark plug and this fixed the problem.

He said he thinks the problem is my fuel tap is dripping fuel even when set to off and this will cause it to flood and foul the plug.

Strangely enough this happened to the bottom cylinder.

Now this cylinder is really blowing smoke, more than before and continously.
Is it possible the rings on the cylinder could have been damaged by this flooding.
I had to drive the bike nearly 10kms on 1 cylinder to get it home.

Or should i just let the bike run to clean / burn of excess fuel / oil?
