Haven't try the DEK on my 200.
Anybody knows how much change in the jetting going from CEK to DEK?
Current jetting:
CEK needle, 3rd nd clip from top
pilot: 45
main: 155
Thx

I'm running a 150/42 combo... middle on the clip. 600 asl

That's a little rich Sheck, especially for an RB'd carb.
I'd drop to 152/42. You will see a nice increase in throttle response, and more top end power with a smaller main.

Maybe others will chime in who run both back and forth, but I'd doubt a pilot or main change would be needed w/ the needle swap.

I have found no jetting change needed switching between CEK/DEK to be
true on both the PWK and the AS modded carbs.
In temps now 50-65 I am running 152/42 #4 DEK and find the pilot
to be a little on the fat side.
EDIT:
With the AS RB modded carb and the head cut for face fuel I found
the 152 lean. Had to change to 155 and now is fine.
