Recieved a volume screw for the carb (there was not one) and removed the section that had been put in place of the screw and spring..... and someone had broken the original off in the hole!!!! great...
Considering it had to come out, whatever, I drilled the old one out with care....
Interesting thing is, I've found out how to remove it without damage to the hole and fuel feed. You start with a small drill and make sure its square to the entrance and end. Bear in mind that i tried all ways to shift it, but its small in there!!
When you drill the second size, if you are lucky (and I was) the tapered end falls off, and you can feel it do so. Then just keep drilling slightly larger till you can tease the rest out...clean up, job done. Its not easy but can be done.
As regards poor starting, I've also cured this as well...
The screw that grips the wire inner to the choke conection had not been tight and had been slipping up and down the wire to not fully ingage the choke to raise the tickover to start the car.
So after all had been done, it started second turn over, with raised tickover (never done that before) so I am very happy.
hope this helps for anyone else.
