First off, thanks for having a look. This is for a 2001 ZXi 1100 with new hotrods crank and Wiseco top end that I'm converting to CDKII. Proper breakin was performed with CV carbs, which is why I decided I don't like them when compared to my XP.
I recently purchased a set of SBT rebuild kits to rebuild a set of 1996 ZXi 1100 CDKII carbs with accelerator pump to replace the non-adjustable/tuneable CV carbs on my 2001 ZXi 1100. I went through one carb at a time and rebuilt them, making sure to spray carb cleaner through all the fine passageways and then blow them out with mild compressed air. (have rebuilt the carbs on my Seadoo XP and Seadoo GTi twice, so familiar with the process) I re-used the stock springs, but replaced the needles with the new SBT ones provided. (Looked Viton tipped?) Tested pop off, which was 26-30 on each, although didn't seem a clean "pop" like I get on my XP. I assume a difference in carb design? While I had the carbs off, I also pulled the intake manifold, inspected the reeds (which were mint) and following another post, sanded the insides of the intake manifold to satin metal finish. I also tapped a 2nd brass barb fitting (placed oil soaked rag in intake to catch metal shavings) for 2nd fuel pump on this set of carbs.
So I get everything back together, with all new intake and carb gaskets from SBT. Highs set to 1 turn out, lows set to 1 1/8 out. Made sure to align throats of carbs to intake to minimize staircase. She fired right up with a little fuel in the throat, but I left the Flame arrestor off so that I could inspect as she was running. Things looked fine, and adjusted the idle up a bit on the trailer with hose, but after a couple short chops of the throttle, noticed the rear carb was dribbling fuel from the high speed circuit at dead idle. The other two were not doing this. If I throttle it up, it seems to go away, but the excessive fuel causes it to idle rough, and I would imagine would cause her to load up over long idles.
Would this be the needle coming off the seat to soon? (low pop off) Or is this the thin plastic diaphragm provided not seating correctly on the high circuit?
On a second note, how the h@ll are you supposed to adjust the high and low on this ski without having to pull the carbs every time? Just seems crazy that to simply adjust the screws up or down, you'd have to replace the base gaskets each time you remove the carbs. Is there a crazy long screwdriver tool to reach in behind the carbs to access the plastic adjustment blades?
Thanks for any assistance you can provide. I am so close, and its frustrating to see this much fuel dribbling off just one of the carbs.
