Redundant information

[Joe_Cole]

From my Mariner Service manual (for Twin cylinder 2 stroke outboard)

"Firing order: 1-2"

That's cleared that up then!

I think you will find shortly after release they had to print an amendment to the manual to cover the mistake. They did blame it on the printers, but I think it was the engineers. So it should read

2-1

It makes a big difference to the engine balance, thank god I am able to give you this information before you do something silly and use the 1-2 formula.

should it not have been 1-2-1 or 2-1-2 to avoid any possibility of confusion?

Reminds me of a couple of old mariners in "The Shipwrights Arms" talking about outboards. One was all for twostrokes. The other was listing the virtues of fourstrokes. One of them suggested that what we really need was a combination of the two. The landlord serving them another pint of Shipwreck suggested "Oh, you mean a Threestroke!" There was a good 60 seconds of puzzlement before they twigged the legpull.

A two stroke can four stroke, but a four stroke can't two stroke......

Reminds me of an old (very old) agricultural pumping engine I saw a while ago. Firing order was something like 1,zero, zero, 2,1,zero,1,zero,zero zero......

Well, at least it clarifies that it's not an Atkinson Differential Engine where you get all four strokes of the piston in one revolution of the crankshaft. Doesn't seem possible does it? However it did (and still does) work, take a look here <A target="_blank" HREF=http://www.lindsaybks.com/dgjp/djgbk/diff/diff.html>http://www.lindsaybks.com/dgjp/djgbk/diff/diff.html</A>.

Two weekends ago I saw an ancient one lunger engine that fired once every 16 revs with a huge explosion that raced it away, and then you could see the speed drop off until the next firing. The mean speed was around 360 rpm. No intake push rod either, it just relied on vacuum to open the intake valve.

The Atkinson differential enagine was fascinating. Great Link.

If you go to any agricultural show or ploughing match and go to the vintage section, there are normally lots of "1 lungers" working, some running on paraffin (originally TVO - tractor vapourising oil, now sadly no longer available).

The smell of a an engine working hard whilst running on TVO, ranks with the smell of Castrol "R", and steam engines as one of my all time favourite smells. Ah, nostalgia.

I always chuckle at "This page has been left intentionally blank" you see in some (usually) electronics manuals.

And actually it isn't blank as it says "This page has been left intentionally blank". It should say "This page has been intentionally printed with the words "This page has been left intentionally blank"".

I know, I'm bored waiting for the football to start
