Another timing belt question

Belts, Plugs, Filters, Fuels, Oils, additives etc..... Told you this might morph into servicing and service items.

However I don't have a Burroughs gauge, and they are no longer avaliable as far as I know, so I'm looking for an alternate way of setting the tension.
They may not be available new, but often come up for sale on EBay etc. You’re most likely to find the generic BT-33-73f gauge. This is the same as the Lotus one, except for the dial scale shows figures, rather than the single mark shown on the Lotus one. The calibration can easily be checked.
I have one of these, but I am not all that sure I can use it!

I have a horrid noise that I though was a failing tensioner, but having changed it it’s still there, the short of noise that might be an over tight belt.. the guage reads just over 90 when cold

Have you removed the ancillary v belts to listen without them?

Ive never faffed around with gauges using the twist method instead, but, if its too tight it sounds high pitched, if its too slack it sounds slappy. Not very scientific I know but.....

I use an Krikit gauge - much cheaper and widely available.

The ever reliable and thorough Tim Engel did a comparison, posted on this post on Pistonheads, you need about ~52 on the Krikit scale.

I printed off Tims advice regarding Cam belt tension many years ago and still refference it today. But if you can accurately gauge 52 on the Kri-kit scale you are a better man than me. Good news is that you don't have to be spot on accurate - do your best to get 52 but slightly off is OK in my experience.
