Thanks boomer...thought it was lefty loosely. Just wanted to make sure. I just bought my 520 H and am partially disassembling her for a good cleaning and some long overdue maintenance.

Hey, what's that little dohickey called that the fuel line goes to that is screwed to the engine cover? Then through the filter to carb.

I am not an Onan guy but sounds like the fuel pump. Should be 3 hoses on it

Fuel pump, hose off the back, through the tin, goes to to crankcase for engine vacuum to drive the pump.

      After using my 8-25 mower successfully for several years I noticed the belts were very worn. I replaced the belts and used the mower several mowings this past summer with no problems until as I was mowing the last time the mower would not move in any gear. After stopping and inspecting the traction belt it was almost completely destroyed. Prior to this I had noticed that the engage/disengage lever was getting hard to activate (very stiff). Has anyone had a similar thing happen?
      Thanks in advance for any help on this problem.
      Just want to keep my mower running.

      I’m trying to restore my grandfathers old 252-H to use around my property. The tires are shot and the rims aren’t too far behind. Anyone have any recommendations for rims and tires that would fit well on it? 
      right now it has 22 x 7.50 - 12 on the back and 15 x 6 - 6 on the front.

      Newb here, recently purchased a b310 that now runs with snow thrower, plow, and mower deck for what I believe to be a good deal for $200. My question to all y’all gurus is what am I missing for my snow thrower attachment? I’d like to get it squared away before winter I know I’m going to need a belt and chain any help would be greatly appreciated.

      I recently acquired a 520xi. She's a pretty sweet machine and I took a liking to her before she landed in my garage. I've used her a few times this spring to haul some brush around in her trailer. 
         As the grass grew taller, however, I knew it was time to put the deck on her and start mowing. Note: this is my first wheelhorse, and also this was the first time I'd mown with her. Anyway, I did about half an hour of mowing (about half of my lawn), having turned her pto on and off a few times for various reasons, when at some point I turned the pto off to back out from between the dead-end swath between 2 trees I had just mown. I backed out, turned around, lined myself up to get back on track with the mowing, pulled the pto knob, and....nothing. Or so I thought at first.
         There is a quiet, though definitely present sound whenever I pull the pto knob on. At first I thought the blades might be stuck or something and the drive belt was sliding on the pto pulley. After some inspection, I found it wasnt. I prooved it wasn't by taking the drive belt off the pto and trying to turn the pto on. I still hear that same sound and the engine acts slightly stressed when I turn the pto on.
         One last thing. I turned the engine off, took the front grill off the tractor and tried to turn the pto pulley. It moves but is stopped by some kind of what looks like a safety stop (a bar on the pulley hitting a bar in the way). 
         Anyway, this is where I'm at. If anyone knows or has any idea why what's happening is happening and/or how to fix it Id appreciate it very much.
