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
