BING Power Systems GmbH - your specialist in carburetors. For more than 85 years, Bing products have been used worldwide when it comes to mixture formation for engines. In the beginning, the focus was on carburettors for the two-wheel industry and for small engines like on our Puchs, but the traditional company has now also made a name for itself as an innovative automotive supplier. Building an original Puch Maxi? Bing still produces the 12mm bing carburettor for Puch Maxi and other models. Even larger versions such as 15mm for tuning your Puch Maxi are still being manufactured.
