If I set the adjustable timing light to 27 degrees, remove and plug the vacuum lines and wind the engine above 3500, should the timing mark line up in the peep hole on the shroud? Am I on the right track?

Very nearly all flywheels should have a mark on them for TDC#1/TDC#3. Fewer fans have a "0" for TDC. The notch on most fans is 27 deg BTDC. If you're seeing that with the engine at 3500 RPM, something may be hosed up.
Check the photos on the Pelican timing your 914 article. They'll show you fans with timing and TDC marks. I believe the 1.8 fans have a notch at ~5 BTDC, rather than 27. It's possible you have one of those and are off by that much. Check the position of the mark(s) relative to the fan blades and the fan supports. Look to see if the fan blades advance (relatively) smoothly as the RPMs increase. --DD |
