Centrifugal advance lockout.

[terry1]

I am using a digital 7 MSD ignition box and I have activated the 10 deg retard on start up.
I never thought of starting problems.I guess that with 39-40 deg of timming and a retard of 10 deg to start the engine,I would still have to deal with 29 or so deg of advance timming to start the engine.Maybe I should re-think this.Thanks for the input.

After more research I noticed that my(Digital 7)ignition programming alows for up to 25 deg of start(ing) retard{below 500 RPM}.That should certainly get me in the range to be able to start the engine with minimal abuse to my starter,I believe.

With a Digital 7 you want the timing locked. You can program timing curve in the software. Locking it should make the pickup more stable. Set up the timing with 2-4˚ retarded in the software and make it up with the distributor to get the timing where you want it at WOT. This will allow you to add a little timing in the software at any RPMs you may need.
