Malossi carburettor kit with 26mm PHBH Dellorto carburettor. This kit is specially designed for the requirements of heavily tuned D50B or EBE, EBS engines. The PHBH 26 should only be used when at least a "midrace" cylinder with appropriate exhaust system has been fitted. The kit is designed for maximum power and top speed together with a high-end cylinder such as the Malossi MHR or the Polini Racing. For a standard 70cc cast iron cylinder this kit is oversized and not necessary.
Compared to a 21mm carburettor, the PHBH has a much larger float chamber and therefore permanently releases enough fuel at any speed. For this reason, the kit also comes with a racing fuel tap that ensures fuel flow under all conditions. A slimming or starvation on long straights is thus prevented.
The jetting is basic and must be adjusted to other components such as the cylinder and exhaust. Overall, a perfect carburettor kit for best results.
