I'll try to pull the motor down this weekend and start a thread on it. The aluminum on the plug was from direct contact with it, the end of the plug was smashed. Either the piston or rod let go, maybe both.

Yeah, Steve, you've got to take it apart and report on the carnage.

Since we've had small engines in here, I like the old K series Koehler single cylinder engines as well as the Wisconsin. Never been that fond of Briggs & Stratton for heavy duty service. Concerning more up to date small single cylinder engines, my pick bar none is the GX series Honda. Not the Vertical piston Honda, the GX has the cylinder leaning about a 45 degree angle. Those things will start...I don't care what the conditions are. Anytime I purchased a centrifugal pump, I didn't buy anything unless it had a GX Honda.

5.9 Cummins , They never had a problem starting no matter how cold or how dead the battery was

and surprisingly a Duramax LB7 A guy I know was trying to blow one up for warranty pourposes , I watched him throw a 1 gallon pitcher of water at the OPEN turbo , sucked it down no problem , while it was idleing he sprayed a full can of ether into the aircleaner , It made some scary noises but was still fine for the time being , he also had my dad plug his Snap on scanner into it and over ride the rev limiter and made it turn 5200 rpm before it stumbled all over its self and wouldnt take it any more , they finally drained all but 1 quart of oil out of the engine and had to drive about 20 miles before it finally locked its self down , True story

The Honda was going to get my vote too, ATCO, but you beat me to it. They would have to be the most reliable small engine I have ever come across. We have one on a pump and I can't even remember when I bought it, it was that long ago, but rain, hail or shine it just starts right up, as do the others that we have. All of the Briggs that we had, were temperamental when it came to starting them.

For the larger engines, I agree with Stock, there was a time in this country when a large percentage of farm tractors, harvestors and quite a few trucks all had Perkins engines and they ran trouble free for years.

These days all of the engines are ultra reliable and it would be very hard to find one engine that stands out from the rest.

I agree that the LB7 is tough (I own one myself), but I call BS. You can't overide the rev limit with a Snap-on scanner ( I have a MODIS). Why drain all but 1 quart? If the engine was so good, why blow it up?

Everyone has their own opinion... mine sides for a 3.9 & a 5.9 cummins, 8.3 was a good one too.

Wisconsin's are good, but grumpy in the cold.

Air cooled duetz are a nice runner, especially tghose between 25 & 45 hp.

International DT466 is a good one...

I'll also agree with the 2cyl JDs and 6cyl in the 4020s.

Cummins 4bt and 6bt engines would probably be near the top for me.

LoL...and being underwater!

Was working the drill rig 180 miles from home in Cincinnati Ohio. Was pumping water from the Little Miami river, which feeds into the Ohio River...very large/long river. Had pump chained to a tree near river. Left one Friday for home, it rained all over the eastern U.S. that weekend, Ohio river came up, backed up the Little Miami. Mon morn, pump gone...underwater chained to tree. 5 days later, able to retrieve pump. Poured the water out of the GX Honda, removed valve cover, rinsed innards thoroughly with Kerosene. Put fresh oil and fuel in it, fired off first crank. Was still using that pump 3 years later when I left drill company. Tough little engines. ;)

My uncle runs a GM dealership's garage and he says that only the GM TECH-II can override the rev limiter for 30 seconds. Superchips programer can only changer the speed limiter so this is bs.

The Honda is the modern day Lister. I have 4 GX Hondas currently. On the Dynapac if you have to pull it twice its got no fuel.

Never met a Briggs worth a cracker.....nothing worse than a Briggs & Stratton on a fire pump..its always gunna let you down when you need it the most.

any opinions on kubota diesels? I have 2 on toro mowers, almost 500 hrs, no probs yet

We have a couple of Kubotas - a tractor and a mower, both bought new by us. The tractor (37 hp diesel) has about 600 hrs. The engine has been good, which is more than we can say about the steering. Two snapped steering rams suggest this is not industrial quality stuff. And it's too bad that the dealer and company did not stand behind the product. Expensive repairs like this should not be required on a low hours machine.
