Not Good Enough

If you think *that* is sludged up, you should have seen the rocker arm covers on a '59 Ford T-bird 352. There was so much sludge that the rocker arms weren't visible. They operated inside a block of sludge, with only room for their motion to take place.
One would think that the valley cover inside the spot welded cover needed to be spotless to work, but they seem to get by without, and all the 'stuff' in there would have stayed in place and caused no problem. The T-bird intake had a separator that was riveted to the bottom of the manifold. Exactly under where the exhaust gas crossover was routed, adding heat for smooth operation when the engine was cold, but cooking any and all oil that got trapped in the separator. Not sure what the reasoning was behind putting the separator there...

Its the truth, people think that rebuilding a small engine is just about pushing the pistons out and putting on new rings, slapping it back together and call it done...

There is a good deal of work involved in just cleaning an engine for a rebuild. An example is the low oil sensor in Honda GX engines. It MUST be removed prior to honing, because it can hold honing grit and metal filings and you will never get it all out.

Another common thing people dont do, just as this guy found out, small engines have breathers, they generally have some kind of mesh to help catch oil mist and keep it from exiting the engine...sludge builds up, and it can block alot of crap up in an engine if it starts to break down.

People think Im kidding when I say that white glove clean is not an option, it is a necessity...

I'm not offended. Auto and small engines are two completely different worlds. Just because you can do the one doesnt mean you can do it on the other.

Not so different anymore...We now have hydraulic lifters, Port fuel injection using open and closed loop Computers, On Board Diagnostics, catalytic converters, solenoid shift starters, liquid cooling, full pressure lubrication, fully electronic engine management systems that control engine speed and throttle angle based on load...

Small engines, in some categories, are more or less downsized car engines...

I disagree with that. What MTD, sears, Troy Built walk behind or riding mower has a onboard computer thats sold at Lowes or Sears? Nothing but switches. What riding mower at Lowes has a tank for refilling brake or power steering fluid?

Please post pic of the mower and pic of onboard computer and power steering brake fluid container.

You need to learn to read a little better. Red didn't say the ones at Lowe's
or Sears had the features he listed. He said they are out there. He also never mentioned a power steering reservoir or brake fluid reservoir.

Btw, what's power steering or brake fluid got to do with rebuilding
of any engine?

Are you just looking for an argument, because if you are, Red is not
the one to argue with about engines.

Here is a Pic of an engine in a X485 JD like mine: http://mechanicsburg-pennsylvania.olx.com/for-sale-2002-john-deere-x485-tractor-iid-220676882 If you look very carefully, you can see the injector harness. Kawasaki FD791 25 HP liquid cooled, full pressure lubrication, electronic fuel injected engine. And yes, it DOES have power steering and even a cup holder.

Who said a darn thing about brake fluid? Did you read my post? :dunno:

And who said anything about MTD? They are way behind the curve on their bottom end lines, but Cub Cadet will have EFI soon if they dont already.

And who cares what lowes or home depot sells...you dont go to the Tom Thumb to get Filet Mignon do you? Just like when Cars were leaving Carburetion in the dust with the advent of EFI...The high end stuff got it first, and as it became more mainstream, everyone went to it.

Here is one example of Kohlers EFI engines, 29hp, Closed Loop EFI, and the onboard computer can automatically adjust to operate on E85 (flex fuel)....Full pressure lubrication, hydraulic lifters, Mahle Pistons, and so on.

As for power steering, Ive had 3 lawnmowers with it...it works exceptionally well, but its certainly not new technology, They had it on lawnmowers in the 80's...

Also the Snapper NXT rider...

Push Button starting
Full lighted LCD display that graphically displays battery level, deck height, time of day, hours on mower, fuel level, and the lowly briggs Vtwin offers their "EFM" technology that uses sensors to determine starting and operating conditions and eliminates the need for a choke and carb adjustments....as well as offering LED headlights...Next up EFI.

Honestly, if you can rebuild a Briggs, you can use those same principals to rebuild any engine.

I've taken apart and rebuilt marine two-strokes, automotive engines and even a liquid-cooled 4-Valve SOHC 450cc engine that makes 56HP and spins to 11,000 RPM - all using the same methods and principals I learned from taking my first air-cooled Briggs apart.

Auto and small engines are not completely different worlds. They may go about doing what they do in slightly different ways, but in the end you still have a crankshaft moving pistons through some connecting rods, and camshafts opening valves.
