My Series III has a 3.5 V8 engine twin carbs. It has always started spot on however resently it will start when cold but not after a short journey(10mins). Eventually it started when I sprayed EasyStart into the air intake. This is the first car I have ever worked on so please bare with me. I have changed the spark plugs the old ones had lots of carbon deposits on them is this usual? Any other ideas?
