Few things are more stressful than a motor that won’t start when you’re blocking the ramp. I’ve been there.
My troubleshooting checklist is simple:
- Check the kill switch.
- Make sure the fuel bulb is firm.
- Inspect spark plugs and wires.
- Look for clogged fuel lines.
Nine times out of ten, it’s something small. Now I run through this checklist before launching so I don’t hold up the line.
