Arrows have a tendency to be reluctant warm starters. Assuming ignition timing is correct and plugs are correctly gapped: 1. Ensure petrol cap breather is clear and not obstructed when you sit on the seat. 2. Ensure the main and pilot jets are clear - have a GOOD look, I once found a human hair in a main jet, removed it and bingo! 3. If everything ok, tickle the carb, no choke, ignition on, 1/4 turn on the throttle, good kick and she should fire.
