Spark plugs question

Probably a silly question, but first time on replacing spark plugs on hustler raptor SD kasawaki engine and instead of using correct torgue wrench of 16 lbs/in I used upper 20s due to mixing up the units. Any concerns of damage on the enginge? Looks fine right now and runs well for the several minutes I had it on

Anything lower than 35 ft lbs will do nothing more than accelerate the wear on the thread & make it a bugger to get out.
Above that and you run the risk of stripping the threads.
Normally you do them up by hand till you feel the plug bottom out then 1/2 to 1/4 turn with the wrench

Upper 20's inch-pounds won't damage any threads. 12 times that would probably be closer to correct; spark plug torque is usually specified in foot-pounds.

Whatever ya do, do NOT install New plugs & torque them to spec in a warm to hot engine. When the engine cools it will contract (shrink) & can pull the threads.
