Is this little hole in the temp gauge for adjustment purposes? There’s a brass tab right behind the hole that connects to the brass strip going to the temp needle.
From the pix of the 3 gauges, looks like the only possible adjustment on these gauges is from the small rear hole where you see the teeth.
My oil pressure is off slightly compared to the Autometer gauge I’m running too
Did you replace your oil sending unit with a repop? it could be it and not the gauge. Most are junk.My oil gauge in the Bee says 5psi and my mechanical gauge says 45 spi. View attachment 1795816
Mines been that way for over 2 yearsYes, have a repop sending unit and I guess I shouldn’t complain with the Autometer gauge telling me what’s up. Factory gauge is about 10-15psi off depending what motor is doing.
