Hi All I have the two Zenith Stromberg I am trying to get them the same When i use the tester for the Idle on the front carb it kills the engine with the ball at the top No mater what I do The rear is fine It seems the slide does not come down as fast as the rear, I did loosen the linkage from each carb Even if I have the idle all the way down it will kill The lower jet I play with its so so Any ideas
