Could have dislodged crap into the needle and seat. Blow them out, refit, run with top off carb and see if fuel level is maintained in float bowl.

Could be a honking great air leak at the manifold. With motor cold (to avoid a fire) spray WD40 around the manifold whilst running. If the engine picks up, it is sucking through a leak.

Cheers,
Harv

Thanks Harv for the fast response
Leaking at the manifold I used the existing gasket!would that cause the problem?
I guess undo and refit?
This is a straight forward exercise , just position and tighten?

Thanks

Yes gasket sealing is extremely important, it changes everything the car needs to run because of the vacuum.

Vacuum effects everything, fuel mixture to timing, if thats not right them no go ! Parden the pun.

Put a new gasket in, the reason is they squash with the first tension and dont spring back, if you move the manifold in any way after that it will more than likely not seal and cause issues.
