Hi Jim,

I used to have the same tendency, my default torque setting used to be "Landrover tight"
I purchased a 3/8" torque wrench (much lighter settings than the 1/2") and started to use that for every little job, (you can develop some easy base settings for say 4mm,5mm & 6mm threads). You start to recalibrate to the new lighter HRC touch.

Also worth having a think, how tight would you put the lid on a jam jar to keep the air out and keep the jam secure inside?...maybe then a 1/2 more of a turn because of the vibrations from the bike...and that in my opinion is roughly your carb rubbers tight enough! Just a nip'n'tweak.
