Hi, welcome to JustanswerYour Honda is set to fire at 8 degrees before top dead centre at idle this advances with increasing revs
This is fixed & cannot normally be altered.To check you will need a timing (strobe) light, connect as per makers instructions.
Remove the small inspection cap on the left side engine cover (alternator cover) & start engine
Shine the light into the hole, at idle speed the 'F' mark on the alternator rotor should align with the index mark on the periphery of the inspection hole
The 'F' mark should progress anti-clockwise away from the index mark as engine revs rise
