<DIV><FONT face=Arial size=2>Jim, Congratulations, that was a good effort!
However, I would like to get a report after 100 hours of
running. When we tried it with a 5hp Petter engine, we cooked the injector
, because it had no fuel running through it to keep it lubricated and cool it
lost all its temper and turned a metalic blue colour and just refused to
operate and we were left with a spark converted high compression
engine. I note that you start it up on diesel and I would suggest
that you don't do any long runs on gas only. Make sure that
you swop back to diesel for a coupleof minutes evey hour or some such
manover. ATB.</FONT></DIV>

conversion fires again on wood gas</DIV>
<DIV><BR></DIV>After some technical drama with a cut trace on the ignition
control board, the Lister finally came to life on Tuesday eve. Ron
Ohler, Mike LaRosa and Jay did the honors, but Ken Boak, Marcus Hardwick,
Michael Shiloh and Peef did much of the preparation that made it
possible. Pictures from the first run are in the workshop gallery
here: <A

time the spark plug it in the COV valve on the side of the head, not replacing
the injector like the last round. This time the diesel injection system
was left intact so we can switch back and forth easily between the two.
<BR><BR>For the first run, we fired it on diesel then switched over to woodgas
while running. It was surprisingly easy to switch over, much easier than with
a carburetor on gasoline, as you could get a sharp switch off of the diesel
via the shut down lever. No usual fuel wandering back and forth as the carb
runs out of fuel.<BR><BR>The timing was fussed with quite a bit. We ended up
with it about 45deg advanced, and it still didn't seem fully enough. One
problem we found with the coil over plug arrangement is you can't get a timing
light on the spark plug wire, as there isn't one. The inductive clamp won't
work over the plug boot.<BR><BR>We had the kill-a-watts hooked up on each of
two legs and topped out at 2.9kw. That was pushing the absolute max. 2.5kw was
easy to maintain. This was at about 600rpm. A little below the standard
650rpm. Shaky shake started above 600rpm.<BR><BR>The compression is the 13.3:1
of last time. The injector is leaking a bit too. We'll likely get a bit more
power once we return to 17:1 and get the injector better sealed.<BR><BR>All in
all, i'm happy how much power it made, and how smooth it ran. It seemed to run
about the same as it did with the spark plug in the injector hole. The biggest
difference was in the timing adjust. so given the lack of good control on that
last time, it is difficult to compare properly between the two modes. But it
was clear that it works just fine in the COV valve, and this is good news, as
this is a better place to put it.<BR><BR>The ability to start on diesel then
switch over with a hard "fuel off" switch was very nice.<BR><BR>Thank you ken,
marcus, ron, mike and the others that made it go. another very impressive
effort by all of you.<BR><BR>jim <BR clear=all><BR>--
