vacuum gauge to solve idle issue

Yes vac gauge is hooked to ported one. The only other port is the one for choke pulloff, which is capped on carb.

OK, but which port are you hooking your vacuum gauge to....hopefully not the ported one for the distributor (finger pointing). If so, that may be why you're only getting 3 in. of vacuum at idle on your gauge.
