I have been trying to recondition a set of 20 years stored TZR250 Mikuni carbs and no matter what I tried I could not get the float pivot pin to budge, I checked dozens of forums and youtube videos, the most common methods are to use a spring loaded centre punch using hand pressure only and/or gentle tapping, heating and cooling and of course the obligatory spraying/soaking in carb cleaner/WD40/degreaser/brake clean/acetone etc. If you have ever tried to remove a stuck pin by tapping a nail or correct sized drift you have probably snapped one or both of the pivot posts/towers, they are very fragile when it comes to applying lateral load (I have done it once before and I wasn't tapping it hard at all) If the pin is just tight (as they usually are) one of the methods mentioned above will work. After soaking in every solution known to mankind for several days, nothing, I also tried levering under the head of the pin with a small screwdriver, nothing, punch and gentle tapping, nothing. So what I came up with was to use my chain breaker tool with a slight modification, I ground a flat face to allow the tool to get closer to the float and allow the hole in the end of the tool to be over the pin head, cut a short length of rod to fit between the posts and then gently tightened the tool and out it came. The chain breaker is still usable as a chain breaker..bonus. I'm sure someone has used this method before but I couldn't find it documented anywhere so thought I would share it. Hope this will help someone to avoid snapping a pivot post and wasting a set of carbs. Cheers
