Vacuum measuring
Vacuum measuring
This is my go to gauge. I’ve had it for at least 40 years, but just had it rebuilt. It was put out by Chuck Wallus who use to make all sorts of BMW service tools.
It is actually a Dwyer 15”-0”-15” Magnehelic.
The action is very smooth and precise. Very satisfying to use. This type of gauge is often used in precision laboratory measurements and widely in the HVAC trades.
Dead simple and accurate. The last carb balance tool you will need.
Cylinder shorting is harder for me on both my twin plugged R90S and R100RT.
