Jim: Yes, I have the correct plugs (NGK BKR6E-11). Just to eliminate
other suspects, I also recently:

* Added fuel injector cleaner (Prestone brand, about 1 month ago)
* Replaced PCV
* New distributor rotor
* Replaced ignition coil
* Oil changed
* New timing belt

(All original Honda parts)

if you bought the correct oem belt, there should be no problem.
inability to get them exactly aligned is highly suspect. in my
experience, when the the cam and crank are set right, they are /exactly/
aligned. it's not as easy to set honda belts as it would first appear,
and as i said before, they're frequently set either wrong, or too slack
so that they skip. slackness is easily detected by "flutter" in the
ignition timing.

tension is set by aligning the belt, turning the crank so the cam
advances 3 teeth [so there's pull generated by the cam lobes/valve
springs], then tightening the tensioner pulley. turn the crank so the
belt rotates 3 full times, then repeat the tensioning process exactly as
before so the run between cam and crank is under the 3-tooth tension
when set. /then/ check the belt timing just to be certain. if correct,
they align exactly. if they're out, slack the tensioner and adjust the
cam one tooth in whatever direction required. do NOT rotate the crank
clockwise at any point in this process!!!

You can't see if the pulleys are aligned or not, because the fender gets in
the way of a good look. Unless one does these every day, it is typical to
check the alignment several times. I never heard of anyone getting it
wrong, and driving it. I suppose that it is possible, but it would run real
bad. The timing marks were jumping around because the old belt no longer
had the proper tension.
