I just bought 2 baja warrior mb200's with what I believe are mb165 engines. The bikes were used hard and I've slowly been fixing them up. I finally got to cleaning the carbs and when I pulled the first on off I discovered that the bowl was held on by what looks like a rivet rather that the normal 10mm bolt. The other carb has the same setup. What gives? Did some models come with non-serviceable carbs? I'll try to find my camera to get a photo of it.
