Primary chain tensioner

[SixFingerJack]

Morning all,
I have a question about the primary chain tensioner.
As I'm rebuilding this motor from boxes, I have no terms of reference for several of the components.
The tensioner blade is secured to the crankcase by a spring steel plate, which is compressed by two nuts.
My question is, how much do I tighten the nuts?
Should the tensioner blade move freely, have some resistance, or be so tight that it will only move by use of the adjuster bolt?
Presently, I can move it by hand, but only with a fair amount of pressure.
 TIA

Just loose enough for the adjuster bolt to move it. Possibly not loose enough to move it by hand.

Thanks very much for the prompt reply, will adjust accordingly.

The adjuster retaining bolts are wired on my engine.

Thanks, I have locktited the studs in the crankcase, and lockwired the nuts to the studs also.
Although this is my first BSA, I already have an unhealthy obsession with thread locking devices and compounds due to previous experience with Harley Davidson's finest.
