Adjusting Float Height on Rotax Max / Dellorto VHSx Carburetors:
Adjusting the float heights in the carburetor is a way of adjusting the fuel/air mixture in the carburetor while still using the 5.2 gram or 3.6 gram floats. (Rotax rules only allow 5.2 gram or 3.6 gram floats to be used in the carburetor.)

A lower float level will weaken the fuel/air mixture making the engine run leaner. A higher float level will richen the fuel/air mixture.Optimizing the float heights can be an effective tuning tool and will improve the performance for your engine .

Adjust the float height by gently bending the float arms to raise or lower the floats in the fuel bowl. Standard Rotax carburetors usually come from the dealer with a 6mm float height. A good starting point is 3mm float height.
