DG or DF?

Dg mate

When cold, the fast idle cam is, or should, come into play.
Initially I would suspect the mechanism is not working correctly.

Do you set the choke before starting?

[colincolin64]

Yes I push the accelerater once then start cheers colin

Mine is auto choke

Auto choke is the standard fitting.
When your engine is cold press the pedal down to set the auto choke. Then go back to the engine compartment and check that the cam on the carb to check that it is set to highest step.
