After idle is adjusted I move to the cam follower adj - this is where I get a little confused. As I understand the book, when you move the throttle, the first mark on the cam follower should start to touch the carb at 7 degrees. If I set that correctly and go to full throttle the carbs don't fully open. How critical is it to be at 7 degrees? I thought mabye the the throttle cable might be bad - it has a little play in it so I have to use the adj screw to to push the throttle linkage back to the idle position. How often do cables go bad - get streched? My current setup, I set idle to ~ 850 (in the water) then lined up the first mark on the cam follower to the carb. I then go to max throttle to ensure all carbs are open. I am not looking at timing except for MAX timing. At idle to ~1100 rpms all is working great then ~1200 - 2000 it is a little rough, after that all smoothes out and it runs good and powers to 5600 RPMS WOT.
