Well, to continue the saga, I have not run
the new 13b much since I got it running a few weeks ago due to the EM2 not
showing oil pressure as it should. It was giving me erratic readings
like -1, -3 etc. I hand propped the engine before I ran it and oil
pumped through the system fine....much onto the hangar floor...alas, the
sacrifices for certainty ;-). Also, during my short runs everything
heated up in the oil system evenly and the oil temp stayed pretty much in
line with coolant temp. BUT, since I was not sure if this was a
gage/sender issue or an actual oil system problem I was very cautious
about my few short engine runs.
Well, today while dreading the idea of
dropping my pan, I happened across an extra oil pressure sender (still in
the package) I happened to have. I had seen it laying around for a
while, but didn't give it much thought until I was thinking about dropping
the pan. Low and behold, The problem was the sender. I am getting
good pressure reading now, along with coolant and oil temp. Yeah. I
am surprised at the temps as they seem to be staying in check considering
the 95 + degree Houston weather.
I am able to start the engine, shut it down
and restart it (something I was not able to do with the old engine).
It is somewhat difficult, but seems to be getting easier as I continue to
tweak things (ie timing). I am trying to do the various tuning via
Tracy's manual. To be honest a lot of the information in the
manual is seemingly abstract until I actually get to the step and/or
problem. So, tonight, I got it to run, and it seems to run better,
but......
I am having a surging problem. It seems
intermittent, but it just may be I have not been setting the throttle
quite the same way as I get use to it all. Also, I have had the coil
C/B pop on me several times now....it seems as if this is when the engine
is near or at idle. I have not had a chance to look into this as of
yet. Also, I have gotten a number of horrendously loud/powerful
backfires. Not sure what changes as the engine may have run
fine. It backfires when attempting to start. I wait a few
minutes and it may then start. Gee, isn't inconsistent crap fun
<g>
I just did a search of the archives on the
surging issue, but have just started reading the 105 post on the
topic. Seems our own Mr. Slade had the same problem back in the
day <g>.
Well, it is the middle of my work week and I
gotta turn in soon, but I wanted to share that it seems as if actual
progress is being made (hmmmm, wonder what will screw this positive
statement up<g>) as the Saga continues.
All the best,
Chris
