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 |

Keep in mind at #1 TDC, could be on exhaust stroke OR compression stroke. Crankshaft turns two times each turn of the distributor.

QUOTE(Artfrombama @ Apr 26 2025, 02:57 PM)  Keep in mind at #1 TDC, could be on exhaust stroke OR compression stroke. Crankshaft turns two times each turn of the distributor. (IMG:style_emoticons/default/agree.gif) Make absolutely sure you are TDC#1 on the compression stroke (both valves closed). I assumed that you’re on Compression stroke when you took your photo of the dizzy drive but assumptions burn us!! Double check before reorienting the dizzy drive |
