Well that was far easier than I thought it was going to be, new diaphram and gasket fitted. Started first time, a bit boggy but I had been tinkering with the carb high and low when my problems first started. Little bit more tinkering and now running perfectly Thank you so much for the advice and guidance everyone But especially Spudulike who helped me have the confidence to have a go. Very much appreciated and my knowledge of carburettor workings is vastly improved

Thank you Spudulike Presume I am not allowed to name the 2 large website companies that are selling a EFCO 141 carburettor repair kit for £32. Your reference to day light robbery is spot on, especially to the unsuspecting like me. This makes sites like this and the people who share their knowledge and experience so valuable. Especially to my pocket on this occasion as the site you linked sell the kit for £4.00. Well after a bit more you tube I felt confident to remove the carburettor and you were spot on it is a Walbro WT 780 . I removed the cover to look at the metering diaphragm and it does appear stiff. So £4.00 kit ordered I will update how I get on when it arrives and I have fitted the new diaphragm thanks for your help and everyone else who has given advice

Well I've been trying to up skill myself (YouTube) on metering diaphragm etc after your helpful suggestions Was wondering if you could give any advice on the carb itself I can get a full diaphram kit ( needle, diaphragm etc) from Efco for about £35 But have also seen under the same kit serial number that the carb is a email oleo-mac 262 or walbro wt-1129 and can buy the individual parts for it. Would anyone be able to confirm this? Also is £35 for for the kit about right? Regards Andy

Thank you all for the advice, it's really appreciated and hope you can further advise Is the metering valve, arm , diaphragm something I can check and potentially fix myself ? As regards pressure testing the carb is this something I can do and how would I go about it Or is it time to take to a professional?

Had this for 4 years without issue However this week will just not idle and then floods on every attempt to restart. What I've tried so far, clear the flood each time and it will start but seems to be running rich have tried minor adjustments to carb and can hear the difference in adjustments when reving . Also wound on the idle screw however all these adjustments have not resolved the issue If I do not maintain throttle the saw dies and then floods on every attempt to restart. I do not know if I am barking up the wrong tree but it seems starved of air somehow but don't know why or the cause. I think this because I started the saw a couple of times without the air filter and housing on and the saw maintained a very fast idle but sounded less rich if you know what I mean. As soon as I fitted the filter and screwed the housing on you instantly hear the tickover drop and sounds like it's running rich and then stalls if I leave to idle. Hence I believe being starved of air. So cleaned air filter, made no difference. Changed spark plug no difference Fitted brand new air filter. No difference. I am at a loss any advice would be greatly appreciated Regards Andy
