Carb Info Help Needed - 3/69 - 9/69 (1 Viewer)

I've been scouring manuals and to my dismay, no luck finding details for the elusive stop-gap carb that is the 3/69-9/69 variant. Part number 21100-60191.

Since they are shared with Crown/Crown MkII and Corona, I thought I'd hunt there but no manuals are easily found yet for any details on float height. The '72 F manual doesn't cover this carb at all unfortunately.

So far the 4M engine of later Crowns with a *very similar* carb has a float height of 13mm, however I don't trust that to be correct since the float itself doesn't match and uses the small sight glass. Before I start filling the bowl and testing various heights - has anyone found a manual that dictates specs for this carb?

Pic for reference.

For those ever rebuilding and missing the pump plunger and discharge weight, the later 2F pin and spring works great, just need to file down the OD and it fits beautifully.

Well - I found an M/2M manual and this will have to be my baseline as it is the closest specs to this carb that I can find on paper. If anyone cares, here it is.

The only potential changes I see so far are that the float below looks like its brass and the choke is automatic vs manual. Aside from that, everything else matches the 3/69-9/69.

Well, I care as I have this carb. Thanks.
