karl1 Posted September 30, 2017 Share Posted September 30, 2017 Hi I have had problems with my bing84 carb running rich for some time. The fault was narrowed down to the choke which was leaking fuel and making the motor run rich. I have solved the problem by fitting a stronger spring onto the choke plunger . This forces the plunger down harder preventing it leaking. Finally got a brown spark plug. Engine is a simonini G24. Quote Link to comment Share on other sites More sharing options...
