So after 12ish years of sitting, I kicked her to life today. It took several kicks seeing as the new Amal Carb had yet to be set up correctly.
However, we did notice one thing about the float bowl.
At the top pin setting, the float needle doesn't completely close off the fuel connection, and thus floods the bowl and doesn't stop pissing out the 2 relief holes at the top.
At the second float setting, it does stop sufficiently (and runs at this setting, I should add), but is very hard to start.
Further, at the second float setting the "tickler" button doesn't appear to touch the top of the float, and thus doesn't cause a flood necessary for starting.
Suggestions on what to do?
Thanks,

no personal experience of this but I did find this a while a go
"Amal float needles used to have only one groove but these days they supply it with two grooves about 1/4 inch apart to facilitate the plastic float which does not have the bow clip on top and uses a throttle needle clip to hold the float in place. So bottom groove for the new white plastic float and top groove for the old style copper or brass float"
OK i trust you have the new type carburetter with the plastic float in it. If so you use the lower groove in the float needle if you have the old style copper float which has the bow clip on top then you use the top notch. That is why they have the two positions on the needle to cater for the new and old float. When the float bowl cap is screwed down tight and you depress the tickler it should touch the float enough to allow petrol into the carburetter.
It appears as though the bottom notch is for the plastic float on my 10 year old 276 carb.
However, the problem arises as follows:
The distance from the top of the float body is 21mm (thereabouts) to the top of the float
The distance from the tickler to the top is 17mm, extended is just shy of 21mm. Ergo, it is not touching the float when depressed.
Thoughts? I know the float can't come up. It runs very nicely where it is once it is started. So the other option is to somehow make the tickler longer by about 3 mm. a piece of small rubber tubing?
Any others encounter this?

Ok just checked a new 1B bowl with the plastic float and the float when bowl held upside down is 19 mil from the top and the tickler touches the float by just over 1 mil at 20 mil. It does not have to touch by much. I would take the tickler out and check to see that there is not a small part of metal stopping it. I use a drop of solder on the end of the tickler and file to allow the small brass top hat to slide over it.
