Hey, Cool ! Thanks, Rob. I've been wanting to build one for some time, but
didn't know how big to make the orifice. I've got all the other parts lying
around my garage, including a spark plug hose and adapter from my
compression gage.

Some sort of restriction is essential, it should be logically between the
regulator and the gage. But the term "close nipple" just means the shortest
possible pipe nipple (typically 1/2" for 1/8" pipe), I don't know what he's
using for a restriction. Perhaps the regulator itself is restrictive enough
for what he's doing ?
BTW, he's not kidding about locking the engine. On my TR3, if I don't hit
TDC just right the engine will turn, even against 4th gear and the handbrake
applied as tight as I can get it.
