Well, yesterday actually. I completed the EAA Sport
Air workshop yesterday on Welding. While I know
the Gas Oxy method it just a BIT antiquated by all
the new stuff, the class removed much of the
mystery involved. I was amazed at the progress
made in just two days. From dripped, blotchy
beads, to "not all that bad", somewhat consistent
beads.
I know it is not much of a leap for many of
y'all, but I always felt quite lacking not having
a base understanding of the process (videos and
books just do not breach the gap). Now I will be
looking for a Tig course, or even, now with a
basic comprehension, even a friends input. The
Velocity is not a big welded craft, but there were
a few things I would at least have entertained,
even if I would have farmed them out anyway.
On the rotary front, since I dedicated a bus
for just the EM2/EC2 and reinstalled the units in
the plane (currently using Rino's old unit since
the wiring is correct for it...my unit has a pin
difference being a later unit), I am
currently NOT having my tach dropping out at 6000
rpm (so far). Last night I did a quick run up
after leaving from the welding class and ran up to
6450 rmp static at about 34.5 MAP. I had trouble
holding it with the brakes...and this was on rough
asphalt. I hope to get out there in a bit and do
some tuning and RE-determine best cranking
settings. It is starting quickly when cold at
full rich mixture. Gotta keep it a full mixture
for a few minutes till it warms. However, it is
taking quite a bit of fudging around to get it to
start hot. Per Mistral, my injectors are large so
I think I may need to go leaner (about 10 o' clock
currently) when hot...or so my preliminary
feeling is such. For those who are not there yet,
you pretty much have to start over with base
mapping every time you get your units back from
Tracy. Of course, I am getting much better at
it...... ;-)
All the best,
