Thanks guys heading down to the smog station tomorrow..... :help:
:shock2:
This is an issue that even the state inspectors I have talked with have been unable to fix because the book they insist everyone own has it wrong.
For the state leave the vacuum retard connected, even if it does not work, and set the timing at idle to zero, then adjust the carburetor mixture to drop you into specs. It will run terrible, but should pass the timing part of the test...
I live in a two speed test area and do not have experience with the dyno tests.
When you get home disconnect & plug the hose to the retard, and set the ignition timing to 10 BTDC. Then reattach the hose. After you get it, then adjust the mixture to best slow idle, plus about 1/8 turn in to get a smooth transition. Then set to your comfortable idle speed.
If you want you can check your timing to see where it's at, but it's not anything to worry about as it will go to 10 BTDC as soon as you open a throttle plate. Besides, most of the TVS switches quit functioning years ago... if everything works as new your timing should be zero.
one of the best things you can do is change the oil before you go in for the test. And of course making sure everything is set to specs, including new filters, really helps your chances.
