Just a quick zoom out to clear the cobwebs (mine and the bike's!) Was having trouble starting when hot, extra choke and handfuls of throttle suggested a fuelling issue...
Pulled the float chamber from the carb (SU), all looked okay.... BUT, on reinstalling the float pivot pin (screws in on these carbs) found the thread was knackered, so much so that it was allowing a petrol weep.
Temporary bodge was to discard the washer it uses to access a small amount of intact thread, flood liberally with loctite and leave for a fortnight...
(If you've never tried putting the float and needle back in an SU in situ: It's fun... NOT!! Definite 'bench' job.
So... New plugs this morning and all appears to be well. Confident enough to stop for petrol, repaid by instant fire up, and each subsequent stop showed a dry carb and no starting issues.
Obviously I will have to do a permanent fix, but given the shallow depth of thread and the need to be leakproof, I expect 'new metal' then tap as opposed to helicoil?? Any suggestions welcomed, thank you.
