quote pugetsoundboater:
I am not familiar with the B Z 7HS. i was told to use B7HS.
The Z means it has an "Inductive Resistor" – to block ignition noise from radios. It does the job without soaking up spark energy like a resistor does. I have these in three of my 15 HP Johnsons (1989-1991) and they work fine, great idle.
