I think the general consensus for a Stihl 029 flywheel is to torque it down to somewhere between 43 - 47ft-lbs.
But I think it's always a good idea to double-check your service manual if you have it or maybe reach out to Stihl directly to confirm?
@Stihl man hmmm, think I saw in the manual that for a Stihl 029 chainsaw, the flywheel nut should be torqued to 20 Nm (14.7 ft. lbs.).
It's crucial to get this right to ensure the flywheel stays secure and the ignition system functions correctly. Always use a torque wrench for this to avoid overtightening or undertightening.
but, Joe is right, though. to make sure, you need to check the service manual
