Well, not for the first time, but for the first time with me in it as it's new owner.



I traveled 1100miles in July to go pick it up.  Then we had to replace some rod ends, and inspect everything well.  Everything seemed to be ready to go, and starter problems cropped up.  By the time I got it fixed, the weather had turned bad, then illness set in for a couple of weeks.



I thought we were ready to go with it last weekend, when I found that I was sold a bad used intercom, and a tach issue.  A new TinyTach, and a new intercom, and it was ready to go today.



My instructor and I flew it for about 2 hours.  Did some basic turns, stalls, stuff like that.  The airplane flew well, and ran pretty good except for one slight misfire on descent.  My instructor was very pleased with how it files, and handles.



I could not be happier to finally get it up in the air, and to start learning on it.  The feel was not all that much different than the gliders I used to fly, if anything it required less input from the controls.



I would like to thank Larry Huntly once again for all the help he has given me in this endeavor.  Without his input, I would still be sitting on the ramp, scratching my head.



OK, now for one question about the 582.  I think we found the issue was that we were running the engine way to rich, but I wanted to ask anyway.  On the ground it would not really smooth out till over 2500RPM.  In the air at 5200RPM, it was fine, but on descent around 4000RPM, we felt a couple of stumbles.  We were keeping the setting verry rich, as we did not want the EGT to go above 1100*.  Once on the ground again, we leaned it way out, and were able to get smooth idle at 1900RPM.



Using the Hacman mixture control, how many turns to the left to lean it out, on a typical day?  The one EGT was reading around 1100* already, the other about 950-1000*.  I did not want to get it too hot, but it may be reading a bit high.

         Congratulations Andrew. Glad to see you persevered. That's a 

lot of difference between the two EGT's. First thing I'd do is 

reverse the sensors to see if one is reading high of if indeed one 

cylinder is that much different. Assuming they're different I'd check 

the plugs for a noticeable difference in color between the cylinders. 

(I'd check anyway.) If different you'll want to check jetting and for 

air leaks, etc.

         Regarding the HACman, I don't remember how many turns it is, 

but it's a bunch. I don't notice anything for at least three or four 

turns, then the EGT's come up seemingly linearly until the knob 

bottoms out wide-open. I get about 80F out of it.

The only accurate way to tell if your temps are right is to yank the plugs 

and look at the to see what color they are.

Andrew,

  

 Congradulations!

  

 Hiccups at 4000 rpm are probably due to over-rich setting on mid-range jet needles.  (I'm guessing your EGT's are pretty low when this happens?) Try moving the circlip on each carb up one notch (leaner). My experience with the Hac-Man is that you just keep turning it until the EGTs reach acceptable levels for the desired power setting. As Guy said, it's a pretty fine adjustment, not alot to be gained or lost throughout the Hac-Man's full range. The macro adjustments are done through carb jetting (particularly mid-range) and prop pitch.

  

 What are you getting for max rpms, static at WOT with your current jetting and pitch?

Thank you everyone for your input.  I am fairly certain that the stumbe was indeed caused by the extreemly lean setting.  We were trying to keep the 1 EGT low, which allowed for real low on the other.  I believe the sensor may be lieing a little bit.  I am going to swap sensor locations and see if it follows, or if it is something with that cylinder.



Full throttle RPM was lower than what it should be, I recall seeing over 6K, but not sure how high, maybe 6300.  I think most of that was due to prop pitch, which for now I am not going to mess with, and being extreemley rich.

Just an update on the EGT issue I had, in case anyone is interested.  I just got back from the airport, went down on my lunch break.  I swapped the sensors around, and then ran up the engine.  The same side of the EGT gague was showing the higer temp, so that means it followed the sensor, and is not an actual reading.  So it looks like for whatever reason that sensor is reading about 100-150* high.



Not a problem as long as I know about it.
