It's getting better > the flat spot is pretty much history.
I installed the primary 8.5 PV, jetted up to 81.
Secondary PV blocked, jetted up to 86.
Tested a nice long cruise at 3800/4000 rpm then shut down to read plugs > no fuel ring.
Then I did a few WOT passes again no fuel ring.
I'm thinking to throw more jet at it > maybe 84 primary and 90 secondaries.
Question, that slight miss at 1500 > when I placed my finger over one of the primary outside air bleeds, the stumble got much worse. What's that telling me??? Also, no brass inserts in the Primary outboard air bleeds.
Thanks for your feedback > and I also believe a 2" spacer may be in order.
