Hello ton66!
Not at all
Those numbers mean nothing to me.
This carby presents as having a float & bowl, and a slide type venturi valve.
That to me is not the common configuration of the Iron Horses used on lawnmowers.
The regular engines would have governor linkage working on a butterfly valve.
Here, the governor seems to have to operate via ... a cable on a slide valve?
Just seems unusual.-----------------------------------
