got it running but...

[Harrison01]

when idling and the choke closed thr seems to be 'hunting' ive adjusted the idle and mixture screw but seems to make no difference. ive also checked all the vacum pipes and they too are all ok.

can anyone shed some light on what it could be.

air leak? Spray some brake cleaner around the joints of inlet and carb, see if engine note changes. Dont spray it onto a hot exhaust manifold though!!

[Harrison01]

i can give that a go
