Tickover revs

[timbigden@icloud.com]

Hi all, tried asking this on the FB page but no luck, so am trying here.
I’ve just fitted a cheap induction Rev counter and want to assess how accurate it is.
For a 1933 standard 2 brg engine what range of revs you expect at tickover also what revs at 30mph in top (4 speed box and 19” wheels).
Thanks in advance.

At tickover as slow as it will run - about 500 rev/min or less. In top gear 2000 revs is 31miles/hour depending on tyres and axle ratio.
