Well, it's been a day. I replaced the wheel bearing in the Escape. Fixed? Why would it be? So, replaced last time with SKF unit. Sound went away but I figured I pushed in the inside grease seal on install. Well, several thousand km later, the sound returned. Old bearing was ripped apart, didn't look bad. New bearing in, while sound is a different tone, it's still there. Felt in the steering wheel on smooth asphalt when turning right and loading the bearing, as well as slight vibration under drivers feet. Well, I have no time to continue this charade so it will go up for sale soon.
My 36 year old Husqvarna 32R had some running issues as well. Starts, idles fine but had a high speed bog or dead spot. Sometimes it would clear up or at least get up to speed. Tore the carb down, did a quick clean and now it barely runs on full throttle. Next week, after work, I'll completely tear it down again, do a more thorough clean and perhaps get some fresh fuel line and filter.
Then my cheapo Troy Bilt 4 stroke power head started rattling. I was using it to till up weeds when it went down. The clutch was coming apart. I had to bend the springs back to seat the clutch weights. Seems to work fine again.
