Throttle Body
- Invert float bowl on bench and remove 2 throttle body-to-bowl attaching screws. Remove gasket. No further disassembly of throttle body is necessary unless idle mixture needle is damaged or idle channels need cleaning.
- If necessary to remove idle mixture needle, cut tang from plastic limiter cap. Do not install replacement. Due to close tolerance fit of throttle valve in bore of throttle body, do not remove throttle valve or shaft.
- California models have seals built into float bowl to seal the power piston drive rod and pump lever to prevent escape of fuel vapors to the atmosphere. Remove seals and retainer prior to immersing float bowl in carburetor cleaner.
