Needle position 376

[RoyC]

My new Amal Monobloc 1" 376 arrived this morning (only ordered yesterday)
It has to have the needle in slot 3.
Where is position 3 counted from ?

Hi Roy
You count from the top.
Should be 4 grooves, so one up from the bottom.

Thanks for that Billy.

Hi Roy,
The new carbs seem to run lean on the original factory settings,
So called petrol is quite different now than 50 years ago
The correct settings are those that work, regardless of what the book says

Hi Roy, that does about sum it up, whatever the engine runs best with, but my Pitmans original handbook says third ring not forth for a 1959 A7SS. But count from the top as said before, I need my extra strong reading glasses to see it now when setting it up. 

Mine is torch on that one however, once again this modern petrol rubbish.   

Good luck with it, still waiting for my air filter to arrive from them, The carb is a far better instrument than th original.

 I see this is a brand new carb  but that looks like a concentric needle.

 Those two little grooves at the top, and only three clip positions...

That isn't my needle (pinched the picture just to ask a question) my needle does have four grooves.

my monobloc 389 needle has five slots (so slot three is easy) , didn't know there was needles with four slots

 I was hoping that was the case, but shouldn't it have five? maybe the new ones are different 

 Bill got in in front....but what he says
