Need info from the '67 CSM

[Duke W.]

Can someone with a '67 CSM look at section 6M, idle speed/mixture adjustment procedure, and tell me what the initial recommended idle mixture screws setting is for the L71 427/435 HP engine center carb... number or turns out from the seat.

Thanks,
Duke

Duke, I don't have one handy but recall initial is 1 1/2 turns out.

I have a few jpg copies of the CSM and it states the the 2300C initial adjustment is the same for all other Holleys.


edit..... Also just googled this and got it from the Holley website. It too states 1 1/2 turns. (Step2)

Duke:

1-1/2 turns out from the seat. This is for engines WITHOUT K-19.
