Too late though. Same issue with me. I have cleaned carburetor. Didn't check wiring though.
The answers I received.
- Clean your carburetor.
- Check fuel filter.
- Always use good oil. Mix it with Hi-Octane
- Check spark plug. Color of spark plug indicates Mixture status
- Check wiring as you said in question.
For me, I haven't checked wiring (ignition coil). Rest of the things are OK.
