Its pretty simple to me... I beat them in with a hammer
and pull them back out with a come-along... what so
hard about that... takes awhile to do all of the valves
but I get them done right.... but what does that matter,
I'm retired and on my CHEAP pension ....
no I just use a fair drag to it... not alot... to
me its a feel... maybe thats why they're called
feeler gauges
