Hello,

I checked the archives on this subject, and they caused me some concern. Does anyone know off the top of their head the timing I should be running for this setup? There are probably several folks running with this particular configuration. I know 10 degrees advanced is the setup for stock (that's where it is now on my stock engine and running well), but I'm in the process of converting to this:

1970 142S B20 engine with:

Pertronix Ignitor
Flamethrower Coil
Standard NGK Spark Plugs set to .005 over factory specs.
Weber 32/36 DGV
Everything else stock

I read old posts saying to simply keep advancing until I hear knock and others saying that this could cause harm to the vehicle. Suggestions? Thanks!

I would go with a bit more advance than stock, only because of the Weber conversion. Try 13-14 BTDC at idle and see how that does. If you detect ANY trace of pinging, back off.

I usually set mine at 20°BTDC and it does well. If your distributor's advance
mechanism is in good shape you could probably turn it to where it idles fastest
and see what it is, and if it doesn't knock and doesn't kick back against the
starter it is probably pretty good. It shouldn't advance much beyond 35-37°
at full centrifugal advance.

Thanks guys, I'll set it to a more advanced timing. The vacuum line to the dizzy has been removed for some time, but I don't think that matters.

Now that I know I need to advance the timing and that it won't hurt anything to advance until I hear a ping\knock I'll do that, use a Colortune to set the fuel\air mixture of the carb, and be off motoring efficiently. Thanks again!
