Howdy all! I don't have much riding mower experience. I work on vehicles and motorcycles. I lived in the desert for the last 17 years and kept the grass that needed cut (if any) to push mower size to save on water.
I recently bought a Simplicity 5216H, 16hp B&S I/C twin with a 36" deck and a snow-blower as my main yard tractor. Now that i have used it for a couple of months and have gotten used to it's personality, I could really use some knowledge and insights before the snow blows please......
The first thing I'd like to deal with is the starter, it sounds like it is dragging or rubbing when I start it up. Is this starter rebuildable, could this just be debris and it needs disassembled and given thorough cleaning, is that even possible? Or is it on its way out?
2nd, how much noise is the drive belt pulleys supposed to make when your foot comes off of the pedal? Nothing appears to be loose, it has a belt that is in good shape, it just sounds overly loud to me. Everything seems to run very smoothly! I have visually looked at all of the pulleys. None appear to be bent or wobbly and they look shiny. The deck sounds smooth and does not shake or wobble.
3rd, it's now backfiring every time i shut it off, nice flame blows out of the exhaust. I pulled the solenoid off of the carb to clean it and i thought there was supposed to be a plunger of sorts, but there is nothing and I'm not seeing any adjustment screws on the carb. So i pull the choke out before i shut her down and she just puffs a bit.
4th, it won't idle down anymore. when the throttle is pushed all of the way down it sounds like the motor is still about half throttle rpm's. I have verified the throttle cable is traveling as it should to the carb and everything is free and moving.
The only issue this mower had when i bought it was the starter issue. i've been using it twice a week since i bought it so i haven't wanted to tear into it yet . I should have a bit of a break to work on it between leaves and snow...i hope.
I've wrenched enough over the years that I can figure out most things but it would be nice to able to pick other brains for a change and have an idea of what I'm looking for before I get into tear down mode.
Thank you in advance for sharing your knowledge.
