In this video you can see the problems that we have with these two Bing carburetors. The main problem was the because of the bad storage of the bike tha water from rain has entered in the carbs and coroded allot of parts. However, I am doing all the efforts in order to recover this two carbs which are expensive to buy. I am confident that I will recover this two carbs because they are very simple, the channels are not clogged anymore after cleaning and we can still buy new original parts for them.
