    long distance logistics profitable?

    The cargo hold of a scheduled airline used to be one of the least expensive ways to ship something. Of course you still have to get it to and from the airports. But the plane is going there anyway and the airline's incremental cost is only a little more fuel and the labor to load / unload.

    JD LA110 Resurection

    Surging usually means the slow jet is clogged. It's not going to come back by itself since no fuel is going toward it at all. It will take a physical cleaning and/or blasting it with spray cleaner. To check the slow jet, with no load on the engine pull back the governor lever which moves the...

    Thermostat opinions - Lower Set point for Summer

    When sitting still, any car will heat up until the fans come on. If you want to modify something, it has to be the fan logic. The thermostat has nothing to do with this. The smart way to control radiator fans is to measure the temperature of the coolant leaving the radiator. When it rises to...

    New Stihl Gas Lawn Mowers

    The small Kohlers at least used to be rather blatant Honda clones. This was at least 10 years ago though (Husqvarna 22 inch mower). I too really don't see the point of these Stihl mowers. Four figure price tag and it doesn't even have a blade clutch? The one-sided handle does look useful to...

    Possible AC issues on the Corolla

    When it is not cooling you need to pull over (leave the engine and the A/C on) open the hood to check if the compressor is actually spinning and if the suction line is cold. If the suction line is cold there is a problem with the controls where the A/C and the heater start fighting each other...

    Is this a phone line or electric?

    That is copper phone line. It is a bundle containing maybe 100 twisted pairs of small wire, each "pair" can serve one customer. You will see oblong splice boxes hanging on the line at various places. These are used where the line had to be spliced because of damage or where it was necessary...

    Walmart removing self checkouts, reported results include significant reduction in theft

    Again the article does not say that. In the story, Walmart made no comments on the amount of theft either in the number or dollar amount. The article only says that fewer people were turned over to the police to be prosecuted for theft. In other words fewer were caught stealing. The...

    2013 Buick Lacrosse cx Hybrid stalls at stop signs

    If it's difficult to get rolling from a stop it's a hybrid problem such as the hybrid battery. A hybrid isn't supposed to run the gas engine much at all in stop and go driving.

    Parts store follies.

    I've never seen metric drill bits in any US DIY-oriented retail store. Yes of course they can be ordered from industrial suppliers.

    What do you think about this electrical work?

    That is a GFCI breaker, required for pool and spa stuff. Pressing the test button should make it trip off.

    Journeyman HVAC question from Electrician

    If the house took a direct lightning hit that blew wires out of the wall, I doubt anything electronic or even just electric is any good. The heat strips should have a limit switch to shut them down no matter what sort of overheat. There is likely a requirement not to use plastic duct close to...

    Walmart removing self checkouts, reported results include significant reduction in theft

    The article only says that police were not being called as much. It doesn't cite any "shrinkage" numbers from the store. With no self-checkouts, "caught cheating the self-checkout" no longer existed as a reason to call police. Fewer people caught does not necessarily mean that theft is down...

    Kohler SV590 engine from LTX tractor to replace SV530 engine on zero turn?

    The cheap lawn tractors with manual blade clutch instead of electric often have a different crankshaft size on the engine. That would be difficult to work around. If the only difference is fuel pump you will need a place on the new engine to attach the fuel pump drive hose. This may be on a...

    Major power grid issues in Portugal, Spain and parts of France

    Well that was a big part of the problem- voltages increased on the Spanish grid as a result of reducing flow to to France and Portugal to try to improve stability. The substations supplying various towns can adpt to a slow increase of voltage by switching transformer taps, but it uses an...

    The reason modern jets have rounded windows

    The intentional outflow is much larger than any leaks would be. Since people are breathing the air inside it is necessary to exchange it during the flight to remove CO2 and bring in oxygen. A leak big enough to affect the system would be apparent in other ways than a pressure test. Something...
