Sparkplug on 346 keeps coming loose

[GardenKit]

Don't know if there is a torque in th huskie manual, but NGK specify 20-30 NM for a 14mm thread in an ally head. I have never torqued them, bur find a lot of finger tight plugs on machines brought in, even from people who should know better.

Anyone know what torque the plug should be done up to?

15Nm from the Workshop Manual for the 346xp.

 

[Generally fingertight + 1/16th of a turn is safe and sufficient].

Gardenkit is right Timesert loads better than a helicoil , won't come out like helicoils do especially when removing a plug from a hot engine , we have the Timesert kit here it's not cheap but you get what you pay for
