Replacement type – parts for my carburetor 2B5 Zenith

Hello, so I have a problem with my carburetor, basically I’m looking for only one automatic starter and a vacuum element for the second stage, for the 2B5 85hp, that’s not easy, I find nothing in the net. So if someone knows where to buy these parts, always likes. Among other things, I have come to the question there is the possibility to use another carburetor from the 2B family. e.g. 2B2…?? without ́interventions ́ like suction bridge adapt…. 2B5 as 85hp and 115hp version what is there to consider if I should stand up for an upgrade to the 115hpler, if available.. Questions about questions, happy osters, and just no thick eggs… in this sense VIEL fun with it. mfG Merlin
