Inlet Manifold studs - modify?
Orcade-Ian:
Ted,
No offence my friend - this forum is all about learning from each other and sharing good and bad. I'm only doing the necessary to this 'James 550'. (did they ever make a 550? My Dad had a 98cc) I'm reluctant to remove the exhaust and other bits at this stage just to make refitting the carbs easier!
I've also got a set of the correct 069 carbs in the pipeline to do the 'bling-over' on, so these will have to come out again - so I will be that 'next guy'. Although I will leave the air plenum and filter box off just to run it in the workshop.

K2-K6:
All good methods and experience to draw from there.
On topic of original posting, I can't see any particular problem associated with going that way. Unsure about rating silver solder but easily check with a sample and tourqe wrench to assess if you feel it has enough security. Obviously if it comes loose in this scenario it particularly low risk anyway.
Understand about balance of thread use if they were to be taken off frequently, but hopefully with good recommissioned set that would be avoided.
On that axis though, you could turn a very simple venturi device (or make one from plastic plumbing fittings) to fix engine side of carb body, then using compressed air to draw vacuum, test the jet circuits to ensure flow from idle, main etc without having to run them to find out if they are impaired.
Sight tube on float bowl and you could judge level drop from single fill to give idea of flow. Or clear plastic connection to carb and shine a torch through while running to see fuel atomisation.

Only problem i can think of is bloody O rings falling out! Evostick anybody?
deltarider:
I've learned to do all carb maintenance with carbs in situ. I can do it blindfolded. Undo the floatbowls is all what is needed. It helps to know what's in there. When you're at it, replace those 16 crossheads by allen bolts.
Oddjob:
I seem to recall the manifolds have small restrictions in the groove which grip the o-ring Bryan so they don't come out. Could be wrong but for some reason it sounds right.
I'll try the method and report back on whether it works or not, when I eventually build this bike that is.
