Wondering what your vacuum guage shows at idle.

I have TIM guage fitted on to the inled manifold and it reads higher (i.e. less vacuum than it should have). Only possible reason is air leak but I have not been able to find one so maybe the guage is out or the vacuum is how it should be.
 
yes it does. I kind of alternate between setting to about 10 BTDC dynamic or if I am bored, advance it until it pinks in third under load then back off a tad; at mo' it is set to 10 BTDC.
