This mercury carburetor synchronizer tuner (carb sync tuner or manometer) uses mercury to synchronize but DOES NOT come with mercury. It will synchronize up to 4 carburetors at a time.
It has a sheet steel body with clear markings incremented every 2cm from 2 to 54 for simple accurate tuning and includes, hose, line restrictors, 5mm (for Honda, Kawasaki and Suzuki motorcycles) and 6mm (for Yamaha and many European motorcycles) adapters and easy to follow instructions for assembly.
Disclaimer: We are selling at a deep discount because the plastic reservoir on the steel body of the Sync Tuner may be clouded which is how they came from the factory yet the unit still does the job.
