Or, in other words, where is a first time engine builder most likely to go wrong?

IIRC That diagram is for a 914/6 flywheel and isn't correct for a /4.
I've had brand new NOS flywheel and compared to those specs it failed. |

QUOTE(Mark Henry @ May 2 2019, 09:18 PM)  IIRC That diagram is for a 914/6 flywheel and isn't correct for a /4. I've had brand new NOS flywheel and compared to those specs it failed. That would make sense because when I measured mine (used & has some wear) I measured C as 10mm with a machinist scale. Not precision for sure but I also don't see any evidence that it started much higher at one point. I also have two other flywheels - I'll take a quick look at those this weekend. Is there any sort of diagram or spec in the Factory manual for the four cylinder flywheel? |
