[More Info]
Racers sometimes will prefer to run without a power valve. In these cases a power valve plug must be used to block the power valve circuit. Furthermore, jet sizes must be increased to compensate for loss of the fuel enrichment provided by the power valve. An increase of 6 to 8 jet sizes will, in most cases, be enough compensation. It is advisable, however, to read the spark plugs and verify proper jetting.
