The experience was just fine. You guys do a great job. I do, however, have a pet peeve that keeps cropping up whenever I buy something that has to be shipped to me. The problem is that retailers have false shipping notification info. This isn’t any fault of yours unless it is allowed to continue. This has been going on for years now and no one seems to be interested in actually fixing the problem. You see, once a label is made, the software sends a notification that a package has shipped. That is an outright lie because a package hasn’t shipped until a carrier has picked it up or it has been dropped at a carrier’s facility. It is likely that it will never change until retailers like you make clear to the carriers that you don’t like their software lying to your customers. Maybe they will then get their software fixed to where it doesn’t tell an outright lie. Not your fault and I’m not blaming you for now unless you don’t fuss at them. So, please shoot an email to your carriers and tell them to fix their software. Thanks for having the fairly-priced parts that allowed me to get my 40 ripping again!

Problem fixed: Loose motor, copilot wouldn’t tighten

It began as a reed inspection/replacement because I noticed a tiny bit of spit-back on carb 3. Turns out that the reeds were fine except for a washer that was dropped into the set behind carb #3 by the previous owner. He’s the kind that needs his tools taken away. That washer sat there with the reed seating on it and somehow barely stayed in place for at least 8 years of moderate use. If it hadn’t, well, that would have probably caused major destruction of the motor. Hadn’t run right for the years that I’ve had it. I just tolerated it running poorly at idle and being floppy. Once I had it running like new, I couldn’t leave it flopping around so began the following repairs: Loose upper mount: Disconnected battery, disconnected all wires, hoses, and linkages connecting to powerhead from elsewhere. Removed trim cover, removed PH bolts, removed PH, soaked old gasket for easier removal, degreased lower cowl/swivel tube with degreaser and hot-water pressure washer, removed shoulder bolts holding brake plate to swivel tube, removed bolts attaching swivel tube to upper mount, removed two good bolts holding upper mount to adapter/exhaust plate, removed mount, removed broken off bolts from adapter/exhaust plate, wouldn’t budge with extractors, drilled/tapped to upsize bolt holes where original bolts were broken off using upper mount as a guide, reinstalled upper motor mount to Swivel tube, Copilot Loose: Removed lower cowl for easier access of hardware and for cleaning purposes. Removed 3/8-16 nut, removed lever, washer, brake plate, and worn-out old discs, cleaned area, reinstalled brake plate with cleaned/threadlocked shoulder bolts, reverse procedure with new discs and nut. Tighten to preference in “loose” position to allow for future tightening. Reassembly: Old gasket was scraped/washed off through the cleaning process. Used new hoses and inspected all electrical connectors. Reassembly was the opposite of disassembly. Thing runs like a top now and tight like new. Man, that washer deal still kinda blows my mind. I’ve saved that washer because of how the reed wore an impression into it. May make it a keychain or something.
