Review on 🔧 Pit Posse PP2590 90 Degree Air Mixture Carburetor Pilot Screw Adjusting Tool Kit - Premium Aluminum & Stainless-Steel Construction - Includes 7 Detachable Heads - Motorcycle/ATV Essential Accessories by Conrad Greene

Machined gears, not cast. Perfect for adjusting the Duel dellorto carburettor on my 2 liter VW engine which has very little space for air adjustment. I say machined gears because they don't appear to be cast. I could be wrong but this is my vision of the design. I know a person who uses this tool and is a Porsche, VW, Audi mechanic. Ideal for very tight spaces. Also included is a handle that you can use to hold on and maintain alignment.
