Multiple Carburetor Sync Tool

A PET Cap with a Boss and 3 Holes to make a simple but very accurate Carburetor Sync Tool, you only need 6mm (or ¼") clear Hoses and a PET Bottle for each Carburetor(throat). Insert 1 Hose in a Cap Hole from the Top until its flush or sticks out a few mm from the Boss inside the Bottle . The other side of the Hose goes to one of the Carburetor (throats). Do this for every Carburetor (throat). Next connect the Bottles together with a Hose but this time the Hose needs to go the Bottom of the Bottles. You need a Hose from the Bottom of Bottle Nr 1 though one Hole in Cap 1 to one Hole in Cap 2 to the Bottom of the Bottle Nr 2 and another Hose from Bottom of Bottle 2 trough a Hole in Cap 2 to Cap 3 to the Bottom of the Bottle 3 and so on. In the “outer” 2 Sync Caps you need to plug one of the Holes. Now you can fill each Bottle with the same amount to about ⅓ to ½ with some colored Liquid and start syncing your Carbs.
