1967 Duetto Timing Question

Hello All,

Stupid question time. I am trying to check timing on a 1967 Duetto, 1.6 liter engine. There is supposed to be a fixed and advanced mark on the flywheel. I have not had luck finding two marks. There is a small notch in the flywheel which was marked by the PO in red, but I can not seem to find another. I'd like to check timing at 5,000 RPM. The red mark is showing up nicely at idle using a strobe. Any idea where the second mark should be ? Thanks.

There should be a P (TDC) and F (static timing) right next to each other. M (maximum timing) will be advanced from the F a ways. Sometimes if you clean the pulley with a solvent, then lightly polish with steel wool or emery paper, you can get the marks to show up better. And try shining a flashlight at an angle to where you think the marks are.

To find the P, turn the engine til #1 is at TDC (put a pencil or something in the spark plug hole and stop when the pencil reaches its highest point, then starts to fall). Look for the P and F marks right by the water pump pointer at that orientation.

My Alfa pet peeve

Andrew is right. There should be three marks. Once you clean the pulley, you can mark them with various colors to see them better, and possibly also paint the marker. Which brings me to my Alfa pet peeve. Only an Italian could put the timing marks on the opposite side of the engine from the distributor. Unless you have six foot long arms, you cannot move the distributor while watching the timing marks to set the timing!
