MIKUNI TMX35 carburetor - 35 mm, manual choke, precisely tuned
The carburetors from the Japanese manufacturer Mikuni belong to the reference class when it comes to perfect tunability and therefore the highest achievable performance with optimum consumption. Mikuni carburetors and parts are manufactured with tolerances of 5/1000ths. This is one of the reasons why they run so perfectly. However, you should take a little time for tuning, as the Mikuni carburetors do not run with just any carburetor configuration, but only with the right one. But then they also run perfectly and you don't expose the engine to the risk of it only running properly in some partial load ranges and then blowing up in one of the other partial load ranges.
The TMX 35 works well on Vespa Largeframe and 180cc automatic engines above 25 hp.
The Mikuni carburettors react quickly to fine contamination of the fuel by overflowing the float chamber. Therefore, ideally use a good fuel filter here.
