Dan Baldwin Posted February 6, 2002 Share Posted February 6, 2002 Just got a set of OER Racing (formerly SK, I'm told) carbs, 3X2bbl, 45mm. Came off of an L31 in Japan. Anyway, I'd like to get a good first guess at jetting for the beast. My engine is a 3.1, 11:1 CR, with a 290/.503" (@zero lash) cam. Jets in the carbs now: 60 pilot air, 220 main air, 165 main fuel. The main air jets look similar to Mikuni jets, main fuel look similar to Mikuni and Weber, pilot air similar to Weber, but one piece, not two (judging from drawings in the "How to Modify..." book). I know this differs from your info, Ruben, any ideas? Anybody know for sure what will directly fit, or do I have to try to source OER jets from Japan? Also, the jet holders don't appear to have emulsion tubes in them. Emulsion function appears to be handled by the jet holders(?) themselves.

Ruben Posted February 7, 2002 Share Posted February 7, 2002 Umm.... It sure does not sound like SK jets. Perhaps what you have are early SK models which, I believe were nothing more than Mikunis or Solex models with SK's name on them. Or perhaps the OER carbs are not SK's. Sorry Dan, I guess I'm not being much help. Ruben '72 240Z Quote Link to comment Share on other sites More sharing options...
