Carb flow testing fixture for testing 4150 style
carbs complete or 1 bore at a time.
Works on all Flowbenches with 5" bolt spacing and a 4 1/2" minimum bore opening. Complete unit includes base plate, 2" spacer, gaskets, hardware, and single bore plate for testing individual venturis. Flipping the plate will allow testing any single bore. Tapped for both bolt patterns but the current 2" spacer fits only the 4150 series carbs. Components are also available separately for your own combination. If you need to test small bolt pattern carbs and have a spacer, buy the base plate only, add your studs and test! Can also be used to flow test custom contoured spacers and air filters on the carb if your flowbench is large enough!
Complete Fixture $225.00
Base Plate only (Both bolt patterns) $125.00
Single Bore Test Plate for 4150 style carbs $45.00
Custom Bore Test Plates $70.00
WARNING - Flow testing carbs that are not 100% dry and fuel free can be extremely dangerous! Any fuel that enters a flowbench creates the potential for a massive explosion and fire!
