    JD X390 hydraulic deck lift is jammed

    Next thing to try is locate your fuse box/panel, then pull one fuse at a time and check it carefully for being blown in the middle or a crack due to age and vibration. This is basic a diagnostic procedure to avoid overlooking anything so simple. If a fuse is bad, replace it with the same size...

    Not Starting, No spark

    Hello ILENGINE: I don't disagree with you, and I have used that same process myself when a solenoid fails. It works sometimes and others not. The other term used for these which is technically correct is "after fire solenoid". After fire occurs when fuel is drawn into the hot exhaust system...

    Hello Jan1985, Did you ever get this figured out? You can get a device on Ebay pretty cheap called a P3 Kill a Watt. It will measure the Voltage a Hz output by plugging into one of the 120V receptacles. Ideally a generator running with no load should read around 122V and 61.5 Hz. Once under...

    Robotic lawnmowers

    Hello C., Get a real gas operated mower and do the job right yourself or spend the money and have someone cut your grass and pick up the yard debris. Robot and electric mowers are simply a "Going Green" fad that is quickly passing. See who still owns (an original) one they purchased in 3-4...

    Not Starting, No spark

    Hi digg7, I think both of you are correct.

It also takes a lot of the reliance away from the fuel float valve as well. As fuel evaporates...

    Why does the new sod lawn have two different blades? Rye? See picture.

    Hi John, I've picked up quite a few chainsaws and weed eaters over the years for this problem. It's simple to fix, but many overlook the muffler and spark arrestor. Sad part is, very few people these days want to buy perfectly good and often more reliable older units like this one.

    FS651V No High RPM

    Hello Hayward51 On these small single and V-twin engines, coils do not often totally fail totally open circuit, but the resin insulated windings rub together.

    FS651V No High RPM

    Hello ILENGINE, I've watched the initial video a couple of times and that popping back into the intake is indicative of badly worn cam lobes or a valve adjustment that was not done correctly. If this original cam design has press on lobes, there may be a chance that a lobe slipped on the shaft.

    Hi Greg R., A governor has only one job and that is to limit the top safe running speed of the engine. Most lawn equipment is limited to a maximum of 3600 RPM (no load). Governors seldom fail or wear out. Most governors come apart if someone has tried to "adjust" them by loosening the shaft...
