The B&S Quantum engine came out in 1986 (?) and has been the mainstay of walk behind lawnmower engines since then. Tecumseh walk power mower motors were all side valves as well until they went out of business. Honda has done the OHV and OHC thing for decades now. A 1990 OHV would be quite rare, I can't even think of what engine that might be.

Sorry to continue the derail, but if you're curious apparently it's a suzuki-made ohv engine used in some toro mowers. Not ours, but it looks very similar to this:

In fact, the B&S Quantum motor is so ubiquitous, we order those slightly rectangular air filters, 491588S, in boxes roughly the same size as a U-Haul size large.

I used to work at Briggs. They package up 50,000 of those filters a month in the summer. If you order them in a 5 pack (4101) thats one of the parts I did.

The engines that came through the warranty department were hilarious. 9 times out of 10 there was no oil in the motor and the customer wondered why the connecting rod turned into powder.

Command >>>> Magnum. There's just no reason to go with a Magnum except packaging. The line ended in the early '00s, but it's already a parts wasteland. You can get more and cheaper parts for a K series than a Magnum.

IOwnCalculus posted:

Yeah, the performance that people need out of a small engine doesn't always necessitate the benefits of a OHV/OHC arrangement. With a flathead you get a cylinder head that's extremely simple, and two valves driven directly by a cam (that can be driven by a gear off of the crank). OHV you need to at least add pushrods and rockers to it, maybe even lifters? Never seen a GX pulled apart.

That said, I do like the OHC GC160 my dad put on our little go-kart. Easy as hell to start and ran drat well once you tweaked the governor to get a little extra RPM.

I've never seen a GX pulled apart either. Or in for repair at all, just maintenance. The new GXes are very advanced, no word yet on reliability. There's no headgasket. The cylinder and head are all one piece. The pushrods ride in aluminum tubes external to the cylinder itself for extra cool operation. You look at the parts break down and you're like :aaaa:

The lead tech at work has been working at this shop 15 years. In that time, he's never had to do a shortblock on a Briggs Vanguard V-twin. Ever. They are vacuum sensitive engines though. Any leaks will result in a mean surge.

Kohler Commands have hydraulic lifters, no adjustments.

Kawasakis have flat tappet lifters and require a valve service every 300 hours that no one does. By 600 hours, though, you're really noticing the wear. $500 later and it's purring like its new. The new FX series had some serious issues. The fuel injected version had its own problems, but all the high horse power engines needed a new camshaft and two new heads. Kaw pays out about $1300 per engine in factory directed mods. They might as well have not even made the engines at all.

lazer-chicken, I forgot about the Suzukis. Those are fun on parts. A fuel needle and seat alone can run $40. Yes, they were hideously reliable.

Sorry for the horrible derailing. I'll take pictures of some ruined Stihls tomorrow.

e: ok I lied, I found some more crap.

3000 series cub with what, IIRC, was a leaking charge pump. Sorta collected all that dirt and crap. I've seen worse since then, but didn't get pictures.

Seconding this, I have the same engine (in vertical configuration) on my lawnmower. Bought it at Lowe's two years ago and it hasn't given me any issues. All I've done is change the oil and run a little seafoam through with the first tank of gas of the season and it still starts up on the first pull (now running on its third season.) I get the feeling the engine is going to outlast the rest of the mower.

I bought a 6 horse B&S Quantum Engine'd walk behind from a family friend and the filter on it was even nastier than these. The pleats weren't even visible, they were buried under all the caked up earth and dirt that it had accumulated. the plastic cover was completely loving full of crap too. After I cleaned the crap out of the cover, put in a fresh filter and plug and changed the oil with some Briggs branded straight 30wt it ran like a champ.

I only paid $40 for the mower because the guy let it get to be run down as gently caress and it barely ran. It still had a decent amount of oil in it, but when I started it before I did the work it would just kind of gain revs veeery slowly until it reached operating speed.

Aww, so I had my slant on. Lay off me!


A few years back I worked for a realtor doing various odd jobs, mostly a lot of maintenance on various properties up for sale. One thing I realized about walk-behind mowers was that more expensive does not necessarily equal better.

He owned a John Deere JS40 self propelled walk behind that I used a few times. Beefy motor (something like 8 "gross torque" or whatever they're calling it now), self propelled, and built like a brick shithouse. However, the heavy cast iron deck and touchy self propel system made it such a pain in the rear end to use.

Most of the time I used my little ~$150 WalMart generic "Weed-Eater" brand mower. I put a Gator blade on it and with the bag removed it would mulch even tall grass into pieces small enough they were invisible in the yard. I really can't say enough about Gator blades. Way better at mulching than the curvy mulching blades that are more common. http://gatorblade.com/

Edit: This has little to do with horrible mechanical failures, I guess. Just more mowertalk ITT.

(horrible maintenance)

To replace the Magnum that I'm rebuilding it would cost around $2500 (short block) and to replace it with the Command, $900. The Magnum has also blown up previously and now needs rings, all before 2300 hours. I have a newer 260K with the Command and 1400 hours and it runs perfectly like brand new. Not that the Magnum is bad but the Command is so much better.

Oh god those poor machines. Those are probably the same people that drive to the next town over to save 10 cents on a gallon of gas but wont buy a $2 quart of oil to maintain something they paid hundreds or thousands of dollars for.

Pro-tip for you guys. Sharpen the blade on your mower more than once a year. I do mine every 20 hours or less. Your lawn will thank you. Unless you have a lovely lawn, then it wont matter.

We should really move to the alternative insanity thread. I could talk about lawn mowers for a long time.

MowerChat!

I've got a guy that lives about two blocks from me that's retired and now repairs lawnmowers for a living. I bring mine to him about once a year to sharpen the blade, change the oil, stuff like that. He's brought it back to life twice now, first he had to take the carb apart and clean it out (hey, free mower), and the second time the jet got plugged. Not bad so far for a free mower. At some point I need to try to get out a busted screw that's one of the mounts for the muffler,...

At the moment, I'm having trouble with the drive gear, I think it's lost a few teeth or something so it stops driving the wheels at random intervals. The guy has a ton of dead mowers he strips parts from (I let him know whenever I see someone dump a mower in front of their house), I'll probably have him fix that the next time I bring it in.

My dad had a Masport mower like that. Was used it for 26 years and pasted down from my granddad. The wheels had no black plastic on them, so they effectivly were just off white rims. It was eventually retired after someone hit a buried 6 inch concrete fence post and bent the crank by about 10 degrees so the blade cut on an angle.

Funny enough, my lawnmower ate it's head-gasket just today. I feared it was a blown rod, as the symptoms where the rip cord seized up half way through pulling it, but there wasn't any metal bits in the oil, and when the head came off so did a chunk of head gasket.

So either I tore the head gasket off and it's throwing me off, or the rod is bad, but I can't imagine it is, as the piston moves freely now that the head is off.

Would I be at least semi right?

Maybe you flooded it so bad it hydrolocked and your puny human arms can't pull hard enough to break something? The gasket was so old that removing the head was the finishing blow?

Gaskets always come apart when you pull the head. You can see a bad headgasket by white smoke coming out around the perimeter of the head. You'll also hear it "tsss, tsss, tssss" when the engine spins down. You would see carbon markings flowing through the gasket region had it been blown. What could have happened is that your ACR failed, or the valves are so worn the ACR does nothing. With the piston at TDC for ignition, try to wiggle and spin the valves and wiggle the piston, no play should be evident. Then have a buddy (or clamp) hold the bail and pull the engine medium speed. Look for the valves to open in an alternating fashion, and the exhaust valve to do a tiny second bump during compression. If no play and no bump, suspect ACR on camshaft.

Reassembled, taped the handle down, and took cover expecting it to eventually reach something like 10k rpms and explode. Never did. Actually It ran out of gas with no drama.

so a head gasket did fix the lawn mower. After getting it to start a ton of oil coughed it's way out of the muffler, and then everything was fine again.
