  3. For the Man-Cup series, the required mixing ratio is 8 ounces per gallon for all two cycle classes
  4. RUNNING ENGINES WHILE KART IS ON STAND:   Engines may only be run on kart stands in their assigned pit areas. They may not be run on the stand outside of the assigned pit area or while being rolled through the pits. Engines may be started on the grid when the karts are on the ground and the grid steward gives permission. This will be about one minute before the karts are allowed on the track.
  5. WKA MEMBERS ONLY IN TECH AREA:   All persons present in the engine tech area must be WKA members.
  6. Participants are reminded about 618.8 -- auxiliary carb return spring -- this is an important safety item -- please review -- this is a post tech item
  7. ENGINE TAGGING -- All engines running in the WKA Man-Cup competition must be sealed using the official WKA engine seal. Any modification, tampering or attempt to violate the spirit and intent of the engine tagging system will result in immediate disqualification. Said infraction will be reported to the board of Trustees and may results in further disciplinary action. All bolts and nuts involved in the sealing process must be thru drilled. Holes should be 3/32” minimum in diameter and should be de-burred or chamfered on the edges to avoid damage to the wire sealing device. The wire must pass through BOTH sides of the nut or bolts being used.
