Default Re: Timing way off - replacement engine in '93 Accord

Can you please verifiy here that the old and new engines
have the same # stamped on them?

Is the car fully warmed up (fan comes on TWICE, then you
check) when you try to adjust the timing (with service check
connector shorted)?

What does the above mean?

You did loosen the distributor housing hold-down bolts and
attempt to get the timing right by rotating the housing,
didn't you?

I know you said you checked it thrice, but IIRC, being
unable to get anywhere in the neighborhood of the three, red
BTDC marks and being 15-20 degrees off still suggests being
off by a tooth. That's maybe not what you want to hear, but
sometimes a systematic approach, when repeated enough,
causes one to overlook simple things...
