I was curious to see the effects of the new timing on a cold engine. Very smooth.

Now, I really want to thank everyone for their input on this. I realize its basic stuff for many of you -- but it feels good to know how it all works. I am sort of the impatient type when it comes to my car -- and having to wait weeks for the mechanic to do this kind of stuff drives me nuts. To be able to ask a quick question and get a good answer -- sometimes within in minutes -- is so incredible. Again, my gratitude goes out to you guys.
 
So, what are these Valve Thingies all about...

so, I need to set the timing on my 66 230 sl.  I found the proper settings for my distro number in the tech data book.

according to the tech data book, i am supposed to leave the vacuum hooked up but disconnect the vacuum arm in the distro. then the tim ing at idle should be 2 +/- 2 deg atdc.

now,  un-hooking the arm  I am guessing is a pain,  so my friend suggested disconnecting the vacuum line from where it connects to the throttle body THEN plug the connection in the throttle body and check the timing.

If the connection at the throttle body is open then the idle will be high and timing may be off.

thoughts?
