Carb dis-assembly tip

Just an FYI,
I have had a few people call me about the fixation screw that is down inside the carb piston in the center barrel that holds the needle in place. This gets removed when you do a full carb rebuild or change the needle clip position. It is a straight tip screwdriver slot and many have tried to unscrew this very tight screw and have twisted the top right off :( and then have to find a way to fix the problem. :ohmy: This screw is held in place with a little blue Loctite from the factory. The best way to remove this is to heat the piston center barrel with a heat gun or take a small butane torch and aim in down and around the barrel that the fixation screw is seated into. Once this is hot the screw comes right out without any damage. :) When putting this back in place do not apply a ton of blue Loctite to this screw. It is a fine thread and a tiny tiny drop will do just fine because you may need to remove it again one day.
I hope this helps save a few frustrating moments along the way. :)
