Vacuum boosters require about 16-17" minimum to be completely effective. That low vac. you indicated would definitely contribute to lower pressure being applied.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
