Hi Grumpy,
OK i have done all of the above.
The float needle is coming out when the float drops down and then reseals when up the float level seems OK very close to 15/16th".

The Engine however is still "Hunting" no matter where i adjust too.
as it is Hunting i have done tiny adjustments until its probably 2 more turns past the original 2 then it seems to stop.
Strange thing is the neighbors mower was doing hunting yesterday i was tempted to go and tell him what he needed to do but wasn't sure if he had a 2 or 4 stroke and whether its different for each.
I'm going to change the fuel/air mix needle to the one from the other carby. Reason is, is the original one when i cleaned it had some black stuff on it and when i was cleaning it i may have damaged it. I don't know grasping at straws now.

Anyway Mate if I don't hear back from you till after Xmas, Thank-you very much for all of your help and patience. And I would like to wish you and your family a very merry Xmas and A happy and healthy 2011.
1 month and 16 days we have been at this. I'll tell you this Grumpy I didn't know anything about small engines and now I'm fluent in just about all the parts, how to break down and reassemble, so if i never get her running at least Ive learnt a lot of stuff.
Take care
Pete
