COMPLETE CARBURETORS
PART NO: PFD63-3709 _ 610 CFM MANUAL CHOKE CHROME CARBURETOR
Here at last from ProFD are the new and improved 4160 model 4-barrel carburetors. These carburetors are equipped with all-new Tru-Set needle and seats, which have eliminated the need for external adjustments. This change allows for easier“ bolt-on-and-go” performance. The floats have been factory-set for optimum fuel levels at 3 to 6 psi of fuel pressure and should never need adjustment. If you’ re running over 6 psi of fuel pressure, a fuel regulator is required. These carburetors also include a new, refined appearance on their float bowls, main bodies, and vacuum secondary caps. Along with having upgraded choke caps for smoother engine warm-up and better cold drivability, these carbs are also the perfect upgrades for any ride.

Taking some development on dyno runs, racers and street heroes alike, ProFD has taken their 4150 carburetors to the next level. Since they’ re aimed directly at optimizing power and performance for racing applications, other important modifications include screw-in air bleeds, stainless steel throttle plates, and notched floats. They also have Dominator style fuel bowls to allow fuel line plumbing from either side.
