A mirror will allow you to see whether you managed to disconnect or fail to reconnect the temperature sender which is beside the spark plug. I've become quite good at reconnecting these with tank in place for reasons which will be obvious. (Insert head banging icon here) Gen2 are much more difficult than Gen1 because the air injection piping takes up some of the hand space.
Glad to hear that you have the carb solved. Acetone is quite effective for removing many types of deposits so a good call on your part. Next time acetone isn't as good as something else so I've found one sometimes needs to try more than one solvent.
Nothing better than high pressure air, so long as one takes things apart so that something isn't damaged. I've seen many traumas over the years where someone tried to clear a carb without removing the float bowl, diaphragm, or other closed space.
Doohickey is a tough one as haven't found a way to see it through the plastic screw plugs in the engine case. I've had to pull the stator (outer) cover to gain enough space to see. FWIW, it requires some attention to detail even with the cover off so make certain that you know for what to look. I look, first, for the torsion spring used by the preferable EM solution.
Gen2 are more difficult because they use an original one-piece Doohickey so first here's what I do for Gen1:
If there's a coil spring in place, I look for the weld which joins the two pieces forming the original Doohickey. Regardless, poke the coil spring (even if has the one piece machined replacement Doohickey to make certain that there is tension on the spring. If the spring isn't under tension, it needs replacement with the shorter EM spring, even if has an EM Doohickey. If the spring is broken, you almost certainly have the stock Doo.
FWIW, if the spring is broken and you wish to continue riding, you can use a long screwdriver to provide spring action to adjust the Doohickey in order to adjust. Then, don't delay, order the kit and install when can. I don't anticipate any problem riding in the short term with a broken spring because of seeing so many broken ones which soldiered on. The broken end piece will almost certainly be in the oil pump pick up screen. I like to clean the pick up screen at this point regardless although discount the level of panic often reported at the amount of silicone "worms" often found in the screen. They don't cause any problems which simply points to how far off is our intuition in these cases.
Gen2 are at once easier and more difficult. If the spring is a coil and has no tension, it is almost certainly an original. One really has to have clean glasses to see the difference in the original (one piece) Doo lever and the one piece EM unit. If it's a one owner 2014 not much question.
Also, FWIW, I'm about 100% on saving the outer housing (stator) gasket and reuse with silicone or flange sealer. As for the inner gasket, I haven't pulled the inner housing for several years as manage to spread the end of the spring to unhook from the peg in the cover without separating the inner cover. Likely done a dozen+ without removing the inner cover.
Hope some of this is helpful.
Shock seals are advertised on EBay and other places by application. I don't see the dimensions in my notes so hope someone has them.
