I just boiled out a pair of new Amals that were lacquered up from non use. When I reinstalled, the left slide stuck. Needless to say I was a little p#&%.
Breath in, breath out. Breath in, breath out. That's better.
I started to remove the left carb. When I loosened the inner manifold screw, the slide snapped shut. Everythings fine. Tighten it up, slide sticks.
Whats going on?? Alignment issues, that's what. The inner bosses where the idle screw would be but are blank, are interfering with each other. When the carb was tightened. it was distorting the body, thus making the slide stick.
Comparing these carbs to other carbs from Nortons, there is a difference. This inner idle boss is machined for clearance on the three 932's on my bench. These all came off of Nortons.
I noticed a set of NOS carbs on e-bay. These idle bosses are also not machined. So beware, new carbs or any parts for that matter can have issues too.
