If your flywheel marks are missing / impossible to see then;
#1 both valves closed with rockers slack? Pull # sparkplug and make sure piston at top of travel Distributor rotor pointing at notch Vacuum assembly on distributor over the hold down nut Not my car, but like this, yes? Look like the right check list? Thanks!  |

QUOTE(Tdskip @ Oct 10 2020, 07:32 AM)  The car is going to be dynamically time anyway so why wouldn’t the position of the distributor and rotor be useful as a sanity check? QUOTE A 914 4 will run will run with the distributor 180 degrees out. If you know your distributor is not 180 out, no problem using the rotor position as a guide. BTDT If in that position, when #1 is at TDC, the rotor points to #3 spark plug tower on the distributor cap. Car still runs fine if the spark plug wires are in the correct firing order relative to that position. A better way to explain it would be to say the rotor, instead of pointing at around 11:00, would be pointing around 5:00. I had a different carbed 914 10 years or more ago that was like this. Ran great. I never changed it. And expecting the rotor to be at an exact clock position is kind of a crap shoot anyway, because timing advance or retard will change the position of the dizzy. |
