That's the right place to hook in the gauge, now just go to a 
hardware store and buy a standard 0-30 or 0-50 psi gauge and 5/16" 
hose nipple to adapt the gauge to rubber hose. While you're there buy 
a couple feet of 5/16" hose to make the connection.

That is the Voltage Regulator and is a good place to take your 
measurements. Take them from the battery side not the generator side. 
These numbers are important, so you need to get a good reading with 
the engine warm and running at med rpm.

Not your problem. Replace it at your leisure.

Why take off the belt? The engine will usually run poorly with the 
charging system not working.

Adjust the valves with the engine cold, then watch the timing marks 
as you slow the running engine down. See if they seem to be 
approaching the right spot. There is ABSOLUTELY no point in 
attempting to search for a perceived FI problem until you are SURE 
you have it timed properly and the advance mechanisms are working.

There is normally only 1. Where are your 2?
