Nope,
No need for shims;)
After figuring out what I did, I had it running in no more than 10 minutes. The af was set at 3 turns out and I could smell it was running a little rich, so adjusted back to 2.5 turns out. Less rich, and then took it for a 10 mile ride.
Need to check the spark plugs to see if they are in the normal range or still running rich.
Is so then need to change out the 42 for a 45 pilot to remedy the rich mix.
But hoping I don't need to do that. But I have a NEW sound to the exhaust with the lowered af mixture setting.
But it runs great. No flat spots.
