setting timing 1962

[johnpaul]

I set the timing because there was pinging when the engine was under load - uphill, accelerating, etc. It worked, no more pinging. However, I subsequently learned that you're supposed to disconnect the distributor vacuum line when setting the timing. The line on mine is the original metal tube. I disconnected it right at the vacuum advance on the distributor. If I'm correct the vacuum should be blocked, but I'm not sure where; should I block the vacuum advance connection point or the tube leading to the carburetor? Also, is it necessary to use a tachometer when setting timing or is it OK to just let it warm up to idle? It seems to idle at a reasonable speed judging by ear.

Block the line going to the carburator.

Agreed. You're setting the initial timing and doing that after it comes to idle is fine.
