Vacume is typically measure in inches of mecurey (inHg). It leymans terms it is how far up a tube (i forgot the diameter) mercury will be pulled at room temperature, if a vacume is introduce at the other side. Make sense??
At idle a good condition rotory engine will produce 18-19 inHg vacume. Excelent condition will be 19-20inHg.

Damn, it did start!
what does fluctuating readings mean. I can only pull14 inHg. and that fluctuates from 12 to 14. The engine is hard starting and floods easy. I am thinking my compression went "poot" Based on vaccum alone, what should I look for?
