SICK BOY Posted April 3, 2004 Report Share Posted April 3, 2004 Vito's carbs are power jet carbs aren't they? Quote Link to comment Share on other sites More sharing options...
gtr370 Posted April 3, 2004 Author Report Share Posted April 3, 2004 Theyre not power jet carbs bought them two years ago I think they are vm28s round slide,I emailed vitos and they said 65 is about right on the pilot size with clamp on filters I guess the pilots are numbered different on these carbs Quote Link to comment Share on other sites More sharing options...
