SO finally getting my S3 Hicap 2.25 petrol going after 2 years. New fuel tank, fuel pump (mechanical) and fresh fuel before starting. Started after blowing through fuel line from Tank to pump and fuel filter before carb. Dows start on choke but now petrol all around the base of carb and looks like from the main carb gasket. Whats likely to be the cause, Stuck inlet needle, float chamber full of ****e? Ta
