With your Fred Flintstone dotted Onesy and wooden club behind you just in case of wantering Mammoths - home delivery meals, even way back then... or the odd Sabre Toothed Tigga....
My shed looks like this most days:

I bought a SuperCheap press a few years back. It is great for most automotive bearings... don't tell Sidchrome, but their sockets make wonderful bearing press drifts. Had a set of banjo bearings though that Would. Not. Give. Bent the 8mm press plates (!), and scared me enough to take it to a diff shop. They squeezed it hard, and there was an almighty bang when it let go. Even they were impressed. I've got a pitman arm under the house in a similar state... should see what they can do with it. Dad bent my heavy cast pitman puller on it, and it flexed the 8mm press plates too.

The 6203 is, I've been told, the commonest ball bearing in the world. It's the drive-end bearing for all Delco-Remy and Bosch generators, and I wouldn't be surprised if it's the drive-end bearing for all Bosch alternators as well.
Ha Ha - mine doesn't - you could never get far enough away to get a clear pic like that - not without shifting an awful lot of gear out of vision.....
I take it Fred hadn't ordered the concrete mixer yet..... "retread" tyre machine...
Well I picked up an old SU HS8 2 inch a couple weeks back and it arrived today - it gives me pause on what to fit now - the 2 inch doesnt have a choke but they must work ok without?
Just love the look of the 2 inch - massive head on it
I think you're right. Or does the "choke" raise the vacuum piston and needle? I've got a book entitled "Automotive Mechanics", published in the UK just after the war, which goes into the theory of operation of the SU in quite some detail, and it makes it understandable too. I could pull it off the shelf and find out. Maybe.
The H, HD and HS SU's obtain a richer start-up mixture (the choke function) by lowering the jet. The HIF uses a rotary valve assembly (not a choke plate).

I'll get it into my carb guy and see what needs doing - there is a big blob of silver solder on the brass flap and the top button has what looks like araldite all over it so suggest that needs replacing - will see if I can get a brass one if that is the case - the rest looks in pretty good condition so a clean up should bring it up nice.
I'll just have to dummy up the choke cable somehow to make it look legit.
The throttle poppet valve is there to protect against overrun. The Strommie carbs have the same. Many people don't like them, and are mindful of them being a potential air leak (lean-out risk). The earlier SUs did not have them. Pretty common practice to solder the poppet valves shut.
Araldyte on the other hand

Cheers Harv - thats great info and yeah the glue on top is very agricultural - looks like the pin has broken through the plastic knob - an easy replacement
