Hatched riding mower

7 posts in this topic

I need to know what has happened. Our riding lawnmower is hurting. A 12.5 Briggs that was running good, my wife turned the throttle to idle, after a short time of cutting, then turned off the key. A backfire and that was the end of it. It turns over very easy and back fires only after turning for 10 or more seconds. Compression check did not even register. Lots of oil in the OHV cap. When I checked it was coming out from the valve guides at a high rate when turning over.

This machine is about 18 years old and only used as a backup and sometime pasture mower. I think it’s hatched, but before I junk it (it’s not worth putting money into) I thought I would ask and see what anyone thought.

PS: Who accepts something like this in the Duluth area,the landfill or some other spot?

While this is just a guess, it sounds like a piston or ring failure. I would imagine you might make a few bucks if you took it to a salvage yard. Call around and see if they'll take it before you truck it out there.

I'm thinking the backfire that happened at time of shut down was the last straw to a problem that was going to happen sooner then later. Hot engine caused from grass or seeds in the flyweel screen. As a result, hotter then normal muffler ignited fuel thats still being pumped as the engine winds down at shut off. Maybe even a small carb gas leak and into the crank/higher then normal oil level. Carbon build up, heat, pop = valve problem.

The piston and rings are probably still good, thats whats pumping the oil past the valve.

Take the spark plug out and slowly turn it over by hand.

One of the valves isn't seating. If your lucky it from carbon and can clean it out.

Worst case you can bring it to Rice Lake Small Engine or Willmans and get their opinion.

Thanks Frank : the oil level is normal, yes the engine could have been hot because on further inspection there was a mouse (rest in peace) nest under the flywheel cover. After removing everything is when I tried to start it again and had more backfires after turning over for 10 or more seconds and saw the oil shooting from the valve guides. A friend of my wife has a son into trying motor repair so I’ll probably give it to him and if he finds out it’s too expensive and can't make any money off of it I’ll take it back and bring it in for disposal.

Demo-Licious in West Duluth wil take it, Scrape yard will want you to remove tires, and all fluids, gas/oil. demo will take it as is.

Might not be bent. My exhaust valve got stuck open do to carbon build up. There is an access panel to the top of the valves and I just twisted the valve stem with a pliers. It popped back. Napa had the gasket and I put in some sea foam and I'm going on 5 months!

    • You'd think they'd give Stalock a look.  His overall NHL stats are OK and not that bad down in IA either....Kemps has to have a "great" night and have everything in front of him going our way to be good...he's not going to steal games for us like Dubs can IMO...give Stalock a shot in the nets!
    • 1 I'm on board, but not sure how you go about doing that. 2 laughably impossible 3 Sure, but it's not going to make a whole lot of a difference. 4 OK, I assume it would need to be replaced with something else though. 5 is open to a lot of interpretation as to what "make no sense"   None of that really puts the power back to the people though.   Do you still envision a representational government with elected leaders?    
    • The fumbling thing and also the blocking and catching the ball where all things that I thought he should have been able to improve on.  To me the failure to improve in those areas seems to indicate he might lack the right stuff upstairs.  With his physical gifts doing something like blocking shouldn't be that hard.  Its not rocket science, you just need to know your assignment and mostly just be in the right position.  Its almost like he couldn't focus on more than one thing at a time.  If he got the ball he could focus on running but not securing the ball, if he didn't get the ball it seems like he couldn't handle the concept of picking up a rusher if need be and then getting out into his route, maybe it was just too much for him to process at game speed.   Like I said he's probably the best runner most of us have ever seen but the rest of his game was so flawed.

    • And trust me, these things will be much easier to accomplish than some progressive or conservative utopia. That is the real pipe dream.

    • Here are few steps, I'm sure you and Del will team up and say they are impossible.

      1. Remove the two parties from power.
      2. Keep money out of politics.
      3. Dump the electoral college.
      4. Dump our tax system - not worth our time.
      5. Dump old laws that make no sense.

      It might even be fun to elect a government who doesn't need to spy on everyone or bail out billionaires but you get it.
       

    • Bahhh ha ha ha ok there champ. More like you see someone else post up a clever meme and a few days later you claim it as you own, often failing to comprehend its meaning in the first place. Of course you do ok with a few of the easy ones.
    •   I prefer a unicorn utopia, but what can you do?   I take it you got nuthin on how you go about "returning the power to the people"
    • Look at it this way, every time a liberal posts something bad about Trump or the Republicans we are proven right. And every time a conservatives posts bad about Obama or the Democrats we are proven right. Is it really our fault that the entire political system is a hot mess? We are just here to point out the ever growing hypocrisy. I haven't seen anyone say they have all the answers, no one does but no amount of polishing those two turds is going to win anyone over.
