Does anyone have any advice on how much to tighten the choke cam mechanism when rebuilding a set of SU HS6s (the bolt head circled in the attached picture)?
When rebuilding my HS6s I have found that if I do this up to anything more than finger tight the whole cam mechanism is bound tight and won’t move - it moves nice and freely if I back the bolt off to finger-tight again but obviously that’s not ideal as it’ll work its way undone eventually.
I have a built-up pair of HS6s as reference but the bolts on these seem to be done up tight.
Am I missing something?

Re: HS6 reassembly - choke/fast idle cam
Problem solved - there is a spacer in the mechanism which looks like it has been deformed slightly by a previous attempt to tighten this bolt (pretty sure I didn't put enough pressure on it to do this but I guess I might have done ) I swapped out the spacer from my 'reference' carb and all is good again now
