Hej! Jag undrar om det bara är att sätta dit denna typ av förgasare utan att göra någon som hellst inställning efteråt? Någon som vet? Mvh Alex Superior performance and drivability in a "Bolt on and Go" performance package. Here at last from Holley are the new and improved 4160 model 4-barrel carburetors. These carburetors are equipped with Holley's 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 running over 6 psi of fuel, 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 warmup and better cold drivability, these carbs are also the perfect upgrade for any ride.
