Crx D16a6 timing belt went got it fixed lost about 1/4 of the HP help

My timing belt went at 10 miles an hour and I had a new one put on
they tested compression and I am about 134 to 139 on all but the #2
cylinder it tested at 129 still within tolerance. I lost about 1/4 of
the power it used to have mainly at high RPM's is my timing off? the
engine was from a japanese Car it says ZC on the block under the D16a6
but it is not DOHC had under 40K on the engine when I purchased it.
any help would be great.

"Slightly" bent valves...

wouldn't that show up in the compression check? it still has great
compression.

yes it would. most likely the timing is not set right, especially if
it's not breathing right at high rpm's. just check it again - follow
the tensioning procedure to the letter as it can easily skip. google
here if you need to read it again - i've posted it before so it will be
in the archive.

recheck your cam timing AND ignition timing.

Compression is OK and not your problem.

I was sort of under the impression the 130 psi range was low for a
Honda. For example, my lowly '82 DX runs around 180 psi. Of course, I
am far from being a Honda expert...
