I'm hoping someone can snap a picture of the distributor with it's cap off - to show where the Rotor is pointing while the engine is actually timed to 27 degrees (the normal factory timing over all the 914 typeIV engines, I believe).
No adjustments would be needed on your end of course - BUT to make the picture usable it would require the photographer to rotate his/her engine to the initial timing "0" degree mark on the compression stroke with the engine off. (your car stays timed at 27 of course) Why do I need this? - because I'd like to get the rotor in the ball-park before my assistant (w/ very limited experience) tries to maintain 3500rpm with my somewhat sticky throttle (to address soon). So, may be kind of a hassle but I'd think it could also help others trying to time their engines for the first time too. We know what the rotor looks like at TDC, but there are no pictures available like what I'm asking for (I looked but couldn't find). I'd appreciate it if someone could help please! ps - if posting the pic is an issue, I can provide my phone# so you can text it to me and I'll post it. LMK |

If you want to know what 27 degrees looks like, remember that the distributor rotor turns at half crankshaft revolutions. What does this mean? 27 degrees of the crankshaft will look like 13.5 degrees of the rotor (or half).
Take a 90 degree angle (like a carpenter's square). Bisect the angle. That gets you 45 degrees. Bisect it again, getting you 22.5 degrees. Bisect it again and you're at 11.25 degrees. Accounting for imprecision in all those bisections and that's close enough. Or use a protractor to see where the rotor will be approximately positioned at full advance. It's really not all that much. But, really how does this help time a motor (other than visualization of rotor position at full advance - which might be useful)? |
