Not sparking every rotation
I have an issue trying to start and keep running my 3W 80 with rcexl ignition unit.
If i manage to get it running it runs fine at top end and will tick over for a short while but then die.
Upon investigation I've found that it sparks on some revolutions but not others.
I've tried different ign units and different plugs and no difference. Also the pick up is brand new
Any thoughts welcome
