INFO-TECH 06/22 – June 1, 2022

All the Tillotson carburetors having the diaphragm p.n.237-162, can be equipped with two versions of the part as shown in the picture: with and without the additional hole. The concerned hole has no technical functions, so it has no influence on the engine performance. 

There are two different tools making the same part, they are fully interchangeable although not identical. We are updating all the tech forms, in the meantime we ask you to consider both solutions as original and valid.
