[Chevelle-list] Timing?

[Pelle Andersson]

I'll try that!

Right now I'm "all over the place" & need to recond my carb first.
As my father used to say "first things first" ;-)
There's a lot of stuff that's been unattended since 70's and if I change one thing
another one is bound to break, you know "the weakest link", "chain reaction" type scenario!?
I'm having a hard time keeping up with her needs (like my GF) ;-)

  What I have always done when adjusting the timing for auto. cars is to set the idle in park at the speed you want it in drive.  Set the timing at the "in drive" idle speed while the car is safely in park.  Also adjust the idle mixture this way.  Then, increase the idle speed enough to get the desired idle when you drop it in to drive.

    At first I did the timing as you described (in neutral/park) and I adjusted it to approx 12*.
    That's the way I've always done it before until I read that "Watson guide" and thought maybe.
    I had problems with the engine stalling when I put in drive which got better when I adjusted the timing "The Watson way".
    I checked the timing with the car "in drive" and It actually changes, quite a lot, 10-15*!
    I had all vacuum plugged & did it "by the book" both times except for the neutral vs drive adjustment procedure.
    Maybe it's the centrifugal advance that's haunting me? When the RPM drops the advance drops too much and it stalls?
     
    I'll double check the timing again and compare the difference between drive/neutral adj. procedure.

    Well, the guide looks good for the most part, but honestly, try this test with the vacuum advance disconnected and plugged... Set your initial timing (around 12* BTDC) with the car in park or neutral. Then have someone sit in the car hold the brake and put it in gear, and check the timing again. If the timing has changed let me know, I'll be surprised.
     
    I also sent an email to Craig Watson, the co-author of the guide asking him if there is a specific reason he mentions this technique. Maybe I'll learn something new after all!

    Guess I was right from the beginning then :-/
    Or have I misunderstood the guide?

    Never heard of that guide, and never heard of setting timing in drive. When you set initial timing with the distributor hooked up, it won't make any difference what gear the transmission is in. It is a simple relationship of the firing mark for the #1 cylinder to top dead center of #1 cylinder. Engine load or even speed (not taking into account for distributor advance weights) will not change that relationship.
     Does the guide give any reason why it needs to be in drive? What do they suggest for a manual car?

    I read the "Watson guide to happy timing" and the stated that the timing should be set in Drive!?

    You should set initial timing with the car at operating temperature and in park. Make sure you disconnect the distributor and plug the vacuum port on the carb.
