Well at least its running, the carbs on them can be a pain in the butt sometimes so I try to get them clean and put in a kit. If they won`t tune or hold a tune after that then it gets a new carb, the ones Hutzl sells work great but need just a little modification on the exterior needle guard to fit into a 026, they are really meant to fit the MS260. I have a few good spare OEM made WT194`s that seem to work best on the 026.
