Spark Plug NGK C7HS gap? By Deleted (Read 1,044 times)

[Deleted]

On the little owner manual book of my scooter, they did't tell what gap i need for the spark plug!?

Is it better to install a iridium spark plug on my 80cc motor to replace the original ?
What is the number and the gap??

What is the advantage of a iridium spark plug?

Thank's!

Gap for the NGK C7HS plug is 0.32" or 8mm. The NGK CR7HIX is the Iridium version of this plug and should not be set no more than 0.36" or 10mm but may actually perform better at 0.32".

Iridium plugs last longer and generally give better performance and better starting.
