This is the "must have" tool for proper tuning of Sidedraft Carburetors. Even the most experienced tuner needs this in his arsenal to make carburetor synchronizing precise and simple. Just place the synchronizer in your carburetor throat and adjust your readings with the stop screw.
NOTE: To further help you, we recommend the Weber tuning manual, see Part #: 1093038.
