I have a 2.2L 911 engine with carbs that I believe has a poor distributor advance curve. As you can see from the picture below the vacuum advance mechanism is locked down with a screw.
 If the distributor was designed to have a vacuum advance then wouldn’t the springs and weights be set up for this? If I set the distributor to get about 30 degrees of advance at 5000 RPM then at about 1000 RPM I am sitting at around 10-15 degrees when I think it should be at 5 degrees. Looking for some advice on this or help on where I should go to get help with this. Jeff B |
