 noisy valve train? Got about 5 hours on a 2012 35 briggs CDI. Checked the valves today they were extremely tight, at 1/4" past tdc could not fit a .001 in there. Adjusted to .005, it took quite a few turns out on both sides. Now I am noticing a "valve tap" that was not there before, really noticable at idle...kinda disappears at over 1200 rpm.
What do y'all think...normal? Thanks

Re: noisy valve train? Did you check it on the compression stroke?

Re: noisy valve train? It is normal to hear the valves. Keep them set within the tolereances and just drive.

Re: noisy valve train? You may want to recheck them- you should hear them but they shouldn't be 'noisy'.
