Pumping?

Need a different explanation here as that's a confusing term.

Are the revs going up and down?
Shaking around bulk?
Like it still wants to go with the clutch pushed in?

It is like a throbbing. / pulsing doesn't matter if the clutch is engaged or not. Revs do not change

Can you shake the motor bulk by hand?
Has it been using any coolant?
What did the plugs look like you just changed?
Has it been using more fuel?
Anything coming out the exhaust?

No you can't move the motor. Engine mounts have been replaced.
Plugs were well used yes using fuel nothing coming out of the exhaust. No using coolant

Sniff the fuel regulator vacuum hose off the rail if reeks of fuel it's probably the diaphragm inside and it's running too much pressure.
