123 Distributor, W/dual 40 Webbers Timing? suggestions?, Setting up the timing .new 123 tune distributor Options

[914lasvegas]

Getting ready to install My new 123 tune distributor with Bluetooth . Not sure where to set the timing for my particular application . Hoping for some suggestions.

Motor is A freshly rebuilt
1.8 from 1974 914
Dual Weber. 40's IDF carburetors. no vac
Motor is installed on a 1965 beetle (baja) BIG tires.

I don't know if the cam was changed .
I do know the motor has new heads on it . But I don't know anything about them.

Besides the 123 tune I also bought a new set of wires and a Bosch blue.

What should I set the rev limiter at?

Any other suggestions regarding my install ?

Any advice would be appreciated .

I am a green newbee.

Thank you .Stewart

Whatever gives you 800-900 RPM AT 8 degrees (7.5) BTDC and full advance 3000 rpm 28 degrees BTDC. So really it only gives you 20 degrees of mechanical advance.
I wouldn't exceed 28 degrees of total advance, but I'd play with any curve that stays within these parameters.
