tickover slowing down

I'm wondering if I never tightened the bolts fully so it was leaking from the get go. Then when I did my first long journey on the hottest day of the year, the carb expanded more than the bolts and sealed up the gap causing my tickover to drop. I then screwed in the throttle stop to raise the tickover which was fine all the way home as the engine never really cooled down. The only bit I don't get is why the tickover wasn't high when I set off for the Essex meeting on Wednesday.
