usually it collects a lot of muck on the end of the carb filter.
remove tank and carb undo carb and lift out gently, on the bottom is a small filter, clean this and main filter. clean out carb with fresh petrol.
check fuel tank also for dirt.
refit fill with new fue. l OK

This happened to a small motor of mine recently - the fuel had caused the fuel pipes to disintegrate and perish - air was being sucked in instead of fuel. Examine your fuel lines.

Good Luck..., February 2016
