Very nice pictures. Is tire changer fastened down? The edge of the rim looks pitted; however, the sealing surface is good

Been cleaning up some of the paint overspray on the inside of the rim, sealing surface and inside in good shape. Installed new valve stems, Amazons choice, but they dont seem as robust as the old ones, hope they dont leak. Iim reaady for tireR Rim ready for tire, so here we go! The lower bead pushed right on with rim and tire all lubed up. The outer bead not so much, I pulled tugged pryed with 3 24 in prybars couldnt get it to stretch on. I then realized i was not able to compress the tire enough with my hand for both beads to fall down into the low area and also pry at the same time. Its really a 2 man job, but im just one old guy so i had to figure that out. Once i got that sorted it went right on. Clamps worked very well. You can see in the photo where i messed up the paint on the rim, even though its on the inside, im still not happy. I will fix that. Before i do another, i will get this upgrade kit for my tire machine, i think it will make things easier. Remember i said i bought this thing against my better judgement, but im having fun so definately worth the minimal investment. This was a great idea a real rim saver, i think the duckhead is plastic so wont hurt the rim if it doent break, but even so you only have to replace the duckhead. I have 6 more to do maybe 10 if replace all the tires on all my quads. Oh man, that sounds disturbing. I must be a glutton for punishment, i would still rathar do them myself at my own pace than take them to the dealer and hurry up and wait to pay them money.

Ok update on the running issues. What's causing this problem is the needle jet gets worn oblong from wear of the needle going up and down and the forward and back pulse of the engine. I removed the needle jet and put a scratch awl up through the bottom and shined a flashlight underneath and you can see the oblong wear of the needle jet. On my customers machine the needle jet is obsolete so I shimmed the needle down with a washer half the thickness of the original and dropped the main 2 sizes and it now runs perfectly. The plastic washer is the oem and the metal washer is the new replacement.
