If you are asking what you will see with a regular timing light, you will probably see nothing. If you are asking what you will see with a grounded test light attached to the closed point arm, with the ignition on, the spark advance rod all the way up, and number 1 cylinder is at top dead center, you should not see the test light lit. If that is the case, with the ignition on and a grounded test light attached to the closed point arm, begin to bring down the spark advance rod. The test light should come on when the spark advance is down about 1 or 2 clicks. If that is the case, you ae good to go on the timing. If that is not the case, follow Les Andrews timing method. All of this is done with the timing pin in the dimple of the cam gear.
