Needle jet help

I've got a momentary blubber when I hammer the throttle, as it comes up thru the rpm's. I'm guessing that its because I'm too on the needle. I've got a R1368M on the 4th clip installed right now. On hand I have a CGK, CGG, and a R1368N. Which needle/clip should I use to eliminate that? Track time is really limited otherwise I'd just start playing. Thanks in advance...

Carb is a PJ, bored to 41mm with a wing deal in it, and a K&N filter. Cr500, ported for top end, 89.5 bore, nikasiled. I'm in Iowa, about 800ft. Running C12 mixed 32:1 with Green Label Blendzall. CR250 Ignition.
Once it gets past the bog it runs like a mofo... just looking for a little better throttle response.

The wing deal... its like one of the "PowerNow" blades made by a company called Scary Fast... not the actual product but same principle. Yes, it has an R1368M needle... just ran out and verified.

I was thinking the same thing. Lean the gas out some or go to a 69 needle.

I dropped the clip to the 5th spot. Took care of that. Ran great last night til the driver/owner/crew chief (me on all 3 counts) screwed the car up. I fired everyone after last night.
