73 1.7 D-jet, vacuum advance stock distributor.
First time I have set the timing on this car myself, but used to doing it on VWs with Type I and IV engines. The fan has two marks, a "0" for TDC, and a red notch for 27 BTDC. Distributor vacuum hoses removed and plugged. Even with the distributor turned as far clockwise as it will go, the timing is (according to the marks on the fan) at least 10-15 degrees too advanced at 3500 RPM. Is the logical explanation that the fan was somehow installed incorrectly? The car was running fine, I pulled the distributor to clean the trigger points. I marked how it was lined up before, so I'm tempted to just put it back, but this is a little unnerving. |

I dont believe the fan can be mounted anyway but correct, nor can the flywheel and both have a notch for TDC.
Cant mount the distributor anyway but right, its notched and cant (no matter what you read on the internet) install it 180 degrees off. You can mount the distributor drive gear off by a tooth and that may explain your issue. static time it at TDC to confirm your distributor is lined up correctly. Simple. Rotate the motor to TDC. Connect a light to the coil, a test light. When it lights up, you are at TDC with the distributor....no matter where it is in rotation... So, you may have your wiring off by one space on the distributor cap, or the drive gear may be off a tooth. Rich Rich |
