Managing Director – Bridge Classic Cars

Our 1977 Triumph Spitfire came into the workshop for the team to investigate some running issues it was experiencing. Classic car technician Jon has begun looking into these issues and already found and rectified some of them.

The first thing Jon did was to charge the flat battery. He then removed and regapped the spark plugs. While doing this he found that the gap on 2 of the spark plugs was closed completely which could be a cause of some of the running issues.

Jon went on to remove and check the carb too.

The video below shows Jon making sure the static timing is aligned and that the rotary arm is pointing to cylinder 1 as it should. The video also shows the advance moving in the distributor when the vacuum is applied.
