12A BP static timing
#28
If I remember correctly mine had a marking that looked kinda like an f but closer to an A. If I am not mistaken I put that to the front, but that was over 2.5 years ago so I can't be sure.
A bridgeport should be able to start with about 15 to 16 deg btc for leading and 5 to 10 deg split. Right? I am going to hook up the timing light this weekend and see where it's at.

I look for the "chamfer" side like the arron cake video on youtube that I watched over 4 years ago. I've never seen an F mark, but the oldest rotary I've ever dealt with is from 86.
And every time I put a front cover on I'm paranoid as hell about that timing gear.

The spark fires when the tip of the reluctor wheel aligns with the sensor. Ignore dots and marks and notches and stuff. Just look at THAT. Put the engine at where you want base timing to be, line up the leading pickup to the reluctor, and you are done. You don't even need a timing light afterwards.
Just make sure that the rotor is pointing to the appropriate leads on the distributor cap, not that you installed the distrbutor 90 degrees out.

Stock timing works just fine on a bridge port. Lesser ported engines like more timing but the higher VE that a bridge port can attain means higher chamber pressures so they need less timing.
0 degrees static is 20 degrees at 4000rpm with a stock distributor. I noted no real power difference between 18 and 22 degrees all-in on my car, loses power past that.
If you tried to set it at 16 degrees base, you'd have 36 degrees over 4000rpm...
