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
