The SI26 will be revised by us so that it also meets the high demands of a strongly modified engine. The Cosa float chamber cover already has a larger float needle ex factory which is additionally equipped with a spring. This effectively prevents excessive pressure at the sensitive rubberized needle tip.
In order to meet the increased fuel requirements of a tuned engine, the carburetor was optimized and a modification made to the through bore between the shimmer chamber and the nozzle block. Normally only 1.5mm in diameter, the FASTER FLOW carburettor already has a 1.8mm bore. This allows it to permanently supply main jets up to a size of 170 with tidy fuel. In addition, we change the float position as this would otherwise be too low in a powerful engine.
These modifications lead to a significantly improved fuel supply, which means that there is no fuel shortage even with very strong exhaust systems. Especially when using an air funnel like e.g. Polini, this measure is extremely important to keep the mixture composition stable over the whole speed range.
Here again all advantages:
Fazit: Very inconspicuous tuning carburettor which already has all meaningful modifications on board and also engines with over 20PS safely and permanently supplied with gasoline!NOTE: All new SI carburettors are manufactured under license by the company Spaco in India. These carburettors have been used in the serial production of Piaggio for a long time. They are of the same quality as the original Dell''Orto carburettors. They also undergo quality assurance at Dell''Orto and are therefore partly packaged in Dell''Orto cartons.
