thomas h. Posted July 16, 2012 Report Share Posted July 16, 2012 So just got the motor back from dune port. And I'm trying to sync carbs and figure out the issue. The idle is ok then I rev it it is slower to rev and I let off and it is slow to return. 4 mill fresh plugs and 25 pilot mid clip stock needle and 340 mains thanks bhq Quote Link to comment Share on other sites More sharing options...
thomas h. Posted July 16, 2012 Author Report Share Posted July 16, 2012 Also I have a sync tool and the idle air speed is 7 hg both sides. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted July 16, 2012 Report Share Posted July 16, 2012 I'm pretty sure that is way to lean. Talk to your builder, they'll know best. Quote Link to comment Share on other sites More sharing options...
Big Bucks Posted July 16, 2012 Report Share Posted July 16, 2012 try a 30 piolt, im guessing there stock carbs, and 1.5 turns out on the air screw Quote Link to comment Share on other sites More sharing options...
thomas h. Posted July 17, 2012 Author Report Share Posted July 17, 2012 Yup got a air leak and I just tryed the 30 p and to bring down the idle the mix screws where closed and the idle was still higher but improved so I think my intake gaskets are bad.

wacko2000 Posted July 17, 2012 Report Share Posted July 17, 2012 Your still lean with a 25 pilot But for starters do a leak down and fix that problem first! 27.5-30 pilot for sure Ask Kevin what he recommends from experience he is usually pretty dam close with his jetting recommendations Joe Quote Link to comment Share on other sites More sharing options...
