48 IDA Float Settings

Yes, you want the distributor to trigger the ignition at somewhere around 10 -15 BTDC, so place the engine at that point, drop in the distributor so the rotor points to number one on the cap.

Nip up the bolt so you can still move the distributor by hand. Connect a non-dial back timing light for MSD.

Start the engine, run the engine above idle to warm up a bit, check the timing at idle, then at 2500-3000 rpm.

Went outside this AM and fidgeted with the car for a bit. Verified the floats remained at the 6mm height I originally set them at. One was WAY low, flooding the throats upon cranking Checked ignition timing at 12*BTDC, which resulted in exhaust pops, so I’m getting spark and fuel. Rotated the distributor slightly clockwise which resulted in carb pops. Wound up breaking a plug wire terminal off in the distributor cap, so I closed up shop for the day. I was going to try bypassing the MSD box with a separate electronic pickup in the distributor, and wire it directly to the coil. However, it appears the 8 pronged inductor(?) is a press fit on the Boss 302 distributor sonthats a no-go. The air gap between the inductor and the original pick up is .008” Beyond frustrated. Troubleshooting a simple ignition issue shouldn’t be this difficult

What spark QUALITY have we got here?

Set up the coil lead with a 1/2inch gap to ground. Crank the engine over with the fuel pumps off.
