Hi Max and welcome. The float hight should be 7mm (not 17 as per the manual) this is measured with the carb carb body turned up and the float is just resting on the needle valve, measurement is taken from the top of the carb body to the top of the float. As regards the slider sticking just remove it and clean the slider and carb body with carb cleaner or a little WD40, do not use anything abrasive on the slider or the body of the carb, it’s probably just some old fuel residue causing the problem and it’s just as well to clean both while you are at it. As you will be removing the sliders it would be a good opportunity to do the slider needle adjustment, if you type “tutorials” into the search bar there is a tutorial there to show how it’s do, it’s a simple job but worth doing. As regards the springs I would leave them as standard. Removing the carb screw’s is always an issue (poor quality soft material) first make sure you are using a driver with the correct size JIS tip, if that fails a small vice grips usually does it, I would then strongly advice going to the “shop” on this site and ordering a full set of s/s carb screws from Marcel and you will never have the problem again.
Hope this helps, Alan.
