My 88 suzuki dt140 starts right up but will only run for about 10 seconds and stalls. It starts right back up but still stalls. The inline ball stays hard, has new fuel filter,fuel lines and plugs. Could this be the fuel pump?
Thanks.
if fuel line is hard then fuel pump should be good. sounds like dirty carbs running out of fuel. can u start it up and floor it for 10 seconds or just idle?
