• Remove any excess carbon deposits with a small amount of carburetor cleaner on a parts cleaning brush. Follow any instructions on the cleaner container regarding cleaner usage.
• Do not use a cleaner containing an extremely powerful solvent such as methyl ethyl ketone.
• Shiny spots on the pintle and seat do not represent a bent or misaligned pintle shaft.
• If heavy deposits are present in the air passage, remove the throttle body for a complete cleaning. Refer to Throttle Body Cleaning Procedure .
