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,
