Specially designed boost bottle for 70cc with rigid vacuum chamber. The advantage is that the mixture no longer runs through the carburettor for a second or third time, but is stored in the boost bottle that is mounted between the carburettor and diaphragm. Acts as a kind of small turbo. Or "BOOST" Bottle. Reduction in fuel consumption and better response and gas flow. Very useful on larger carburettors that run rich low down.
Supplied with boost bottle and all parts for installation.
Available in: chrome and anodized blue .
