Thank you Wristpin ........ much appreciated ! I've just been given another 'Twenty One' (not running) so can experiment on that one first.

Hi all New to this site so sincerely hope you can help. I'm sure this has been covered before but i've recently acquired an Old Hayter Twenty One which is a lovely old machine. Its reluctant to start without a splash of fuel down the air intake but once going runs and cuts beautifully. My question is once the going gets tough forward motion struggles so i'm pretty sure the clutch is slipping. Does anyone have any instructions how it can be adjusted ? If it helps the version i have has a castellated nut on the axle. Many thanks in anticipation !
