Well, I was wondering a few things. I have a 68 Chrysler 55hp and wanted a new carb float for it since it still had the old cork material float that has been prone to getting water logged....I replaced this cork float with a F10346 Float, which is a Mercury Quiksilver float...Ever since I replaced the float and adjusted float height both ways....the boat lacks all the acceleration it had before I replaced it...The carb number is a Tillotson WB5A and couldn't find anywhere on the internet of this float being compatible with this carb. I purchased the float from a marina in northern new york and suspecting the wrong float they gave me??? Does anyone have any idea on the compatibility of this float with this carb? Any help would be greatly appreciated....
