[TR] Overdrive Dial Indicator

[TERRY SMITH]

It appears that in order to adjust the TR3 Type A overdrive, I'll need to do it correctly.  Darn that anyway!  I think that somehow a dial indicator is inserted where the operating valve plunger goes.  Will be searching for videos how to do that.

Meanwhile, any recommendations where to purchase a decent dial indicator for someone who's not likely to use it too often?

Thanks for your thoughts,

New Hampshire, where a heat wave brought us to 20 degrees yesterday and 32 today!  Fuel oil deliveries are two weeks out because they haven't been able to keep up.  (S'okay.  I can use diesel but it's a buck a gallon more mostly due to road taxes.  And too that's why I cut and split firewood every summer....) Not top down weather here.
