I noticed my Dr D hotstart lever wasn't working last weekend so as I tried to take it off the carb but the plunger is stuck. I loosened the cable enough to peek in there and saw that there is something that has practically glued the hotstart plunger into the carb. Has this happened to anyone else? Any ideas how to get it out? I have already sprayed some carb cleaner in there but that hasn't helped I'm at a loss and I don't want to break the carburator.
