Adaptor long version for synchrometer

Synchrometer Flow Meter is designed to measure the air flowon the air intake of the carburetor. The indication is moresensitive on the lower side of the scale to ensure most preciseadjustment at idle and low R.P.M.

Type BK futures a rubber sleeve that can be rotated to open a bypassto allow a higher air flow. It fits to the outside diameter ofapprox. 2 inch (48 to 53 mm Ø ) without adaptor.

Type SK with a rubber cone is ideal to fit inside ram pipes andintake bores of 1 5/8 to 2 1/8 inch ( 40 to 55 mm Ø ) without adaptor.

While a single instrument is sufficient, the use of two matchedSYNCHROMETER instruments has many advantages:The instruments stay connected to the carburetors and thehands are free to adjust and accelerate etc.
