Bests & Worsts Reviews from Amazon

I bought one of these about 5 years ago. I have been using it about every other day since then. About a month ago it started getting oily and making some noise while running, so I partially disassembled it and tightened all the bolts I could find with a Torx driver (almost every bolt in the thing uses this, very convenient for a DIY type person who has the right tool). After reassembly it ran fine again. Fast forward to yesterday - with a full tank of gas I went on our roof to blow off the accumulated leaves and debris from Hurricane Irma. The blower worked great, though I noticed that toward the end of that session it seemed to lose a bit of power, and it got all oily again. When I hit the kill switch after cleaning the roof it stopped more abruptly than usual. I just disassembled it all the way, and I found that virtually every bolt in the thing had come loose again, and one of the block mounts had broken off entirely. I didn't separate the head from the block, but upon rotating the shaft, it's clear from the rotational play that the connecting rod is now way bigger than the crank journal. It actually rattles inside. So... After many hundreds of runs it's clear the little finally engine reached its design lifespan, doing its job until it just couldn't run any more. I'm about to order another one just like it. The broken one can donate parts if needed. -Noel
