You all may recall my annoying no-start of a week ago after a routine tune-up. I got it running poorly, but had to leave town for a week. I was hoping the beast would heal itself. No such luck.

Here's the deal:

Timing's good, plug wire order is good, dwell is good, valve clearance is good.

The motor will run on cylinders 1 and 2, but 3 and 4 won't fire. The exhaust runners are cold.

There is spark there (I checked by using one of the old plugs on the block.) There is apparently fuel, because when I pulled the new plugs to check the gap, they were wet.

What to check next?

This quote from Winston Churchill seems apropos:

"Never give in--never, never, never, never."

Thanks in advance,

Steve M.
