Looks like a Monobloc main jet cover. Maybe you turned a taper on the bowl, to match it.

Can you provide info on what size Dowtys you used?When they started spoiling good petrol with ethanol, I fitted Viton Dowty washers to the later metal drain plugs, they work fine and you can drain the carbs as often as you like and re-use the washers Stato seals would also work.
They need to be tighter than just compressing the lock washer or will back out. Have had it happen to me so I am less worried about warping the bowl than being stranded. The philips head bowl screws will not allow you to get them tight enough to prevent backing out, in my opinion. Flat head or hex head bowl screws are better.You probably already know, but on Amal carbs you should only tighten the screws until the lock washers are flat - it's real easy to distort the bowl and make them leak by over tightening.
Weird. Never had any come loose in 52 years and I've never had a customer complaint either.They need to be tighter than just compressing the lock washer or will back out.

Same here. Hardly ever bother changing the gasket either !Weird. Never had any come loose in 52 years and I've never had a customer complaint either.
Yes it is and they come with a taper that seals without the need of a gasket. I used them for many years on a 500 twin race bike and they worked perfectlyLooks like a Monobloc main jet cover. Maybe you turned a taper on the bowl, to match it.
The drain plugs were purchased from RGM, the 14mm Dowty washers were purchased from a hydraulic hose replacement companyWhere did you source the plugs and Dowty’s?
Any more info or pic. What brand of ratchet?miracle micro-ratchet and hex bit,
No, that's wrong fuel (float) height or bad float needle - you're continually flooding.Any more info or pic. What brand of ratchet?
Just got 73 850 with small rt carb gas leak. Replaced gaskets & put in stay up floats. Still leaked= traced to fuel leaking out around base of tickler when engine running. Is that a bad o-ring? Can't find a diagram of it.

Several folk have reported exactly that !" New stays ups have a different recommended setting than originals."
Good upgrade for the Premiers is replacing the stay-up floats with the originals!
