I've already drilled the plug out, but here's the location: If any of you are handwriting analysts, please keep quiet. Oh, I guess you could tell that already...

Only with a cv carb the slide position is not directly related to the twistgrip. Clive W

As Bobo pointed out the hardwired carbs are a lot more to punch, you get a moment of bog if it's rich enough and then bang - do they actually run much better than a vac operated - I doubt it - but more fun -

anyway - don't you think the idle mixture carries up about the same place 1/4-1/3 on a CV vac carb - maybe even longer as the "lazy" vac slide takes it's sweet time to pull the needle out

No need to measure the vac, it's the pressure between the engine and the throttle (blades on stock carb, slide on the amal).

You may have to drill and tap to put a fitting in there, forward of the slide in the neck of the carb... No big deal.
