Ok so I rebuilt the card on my 1971 Skitwin 40 hp. Just got it firing good after a coil replacement and a carb rebuild. Ran great for bout an hour then on way back home checked the engine while under full throttle and the high and low speed needle was moving all over the place. Then noticed the low speed came out with a silver bushing. I redid the packing did I do it wrong? Did I rebuild wrong? Any help is appreciated. Some of the cork gasket material came out also with the needle.
