Finally got around to adjusting the air/fuel mixture screw. I was getting popping on deceleration, which I am told means it was running lean. This went away after making the air/fuel mixture... Fatter?
The basic procedure is to remove the plug in front of the adjustment screw, tighten said screw, then untighten a certain amount. The hardest part of this is removing the plug due to it's orientation on the bottom of the carb. Some stuff I read said to remove the carb, but rotating sufficed for me. Once the plug is removed you can easily enough get a short screwdriver in there to adjust.
I know many have done this, but for some reason I could not find pics of the procedure. Thought I'd make some as I went.
Step 0: Turn on some tunes. I used the Ghost album Ceremony and Devotion in this instance.
Step 1: Gather tools. I used a JIS screwdriver, small flathead screwdriver from a eyeglass kit, needle-nose pliers, Robinson screwdriver and a small screw.
Step 1a: Feel sorry for those who do not have access to Robinson or Torx screws. They make one handed operations much easier. Helps when you are ham fisted.
Step 2: Loosen carburetor front ring clamp (I think that's what they are called) to help allow easier carb rotation. Mine seemed to rotate without doing this, so this step may not be required.
Step 3: Loosen carburetor rear ring clamp. Again, you may be able to skip this step.
Step 4: Turn the handlebars to the right to release a bit of tension on the throttle cable. Rotate carburetor bottom out 45 degrees towards the choke side. This takes a bit of force so just rotate enough to access the bottom of the carb. If you feel you have to twist too hard, you may have to remove the carb.
Step 5: Thread screw into hole in plug. I think that older TWs don't come with a hole. If that's the case, drill a small hole being careful not to mar the brass screw underneath.
Step 6: Pry out plug. I forgot to take a pic of this step and had to edit the picture using advanced photo manipulation software. If you know what to look for you may be able to see where I altered the pic.
Step 7: Return carb to original position, and tighten clamps. I suppose you can adjust the air/fuel mixture screw at this point, but I didn't.
Step 8: Mark screwdriver to help when counting rotations.
Step 9: Gently turn screw clockwise until it's all the way down. My screw from the factory needed about 1.75 turns. Now turn counterclockwise 2.5 turns.
Step 10: Go for a ride.

Husqvarna 6440 - she may be old, but she still runs like a sewing machine.

The Manracks is my personal favorite rear rack for the TW, but as you, I also have concerns about the seat being leveraged off by a load on the rack.
I'm glad to hear that you have not seen this to be a problem so far.
I have not purchased a rear rack yet but I am most likely going with Manracks.
Well I put a license plate on mine today, so I'm official! Rode around the valley, and found the top end on my little mule. 67.
Got those Pro Taper ATV High bars installed yesterday before some wintry mix comes in today.

You must be single or married a bike gal....my wife would kill me for working on the bike in the house!
I didn't take a pic ... because I was busy running around going other things too; however, I washed the bike yesterday, then cleaned and lubed up the chain. It was pretty muddy from the last few weeks and needed a nice polish.
I had intended on adjusting my jetting and needle a bit to get it running a little richer—definitely running lean currently from factory. I should be able to get to it at some point this week, but I am adjusting the main jet from a 126 to a 130, and will be adding a washer or two for the needle. I have an aftermarket DG Exhaust coming from Amazon, so trying to get that done before the pipe gets in.
