    weak spark

    Getting zapped through the boot says that spark may be better than you thought, but could also be ‘leaking’ to ground if the plug wire is chafed somewhere. That’s not likely with a new coil and wire assembly though unless you were less than gentle with installing it. It also says the plug may...

    Predator 9500 Generator backfiring on shutdown.

    I took a Vocational Agriculture class in high school. The instructor worked out a deal with some of the local small engine shops to supply parts and engines for teaching, both 4-stroke and 2-stroke engines. Back then 2-strokes were pretty much exclusively used for chain saws. He kept a bunch of...

    Predator 9500 Generator backfiring on shutdown.

    Yup, I know exactly where it shuts off the fuel. And I meant exactly what you pointed out, that the float valve often swells and fails and hydrolocks small engines that are stored for long periods. The solenoid valve on my Intek 22HP is actually the main jet and solenoid valve all rolled up...

    Predator 9500 Generator backfiring on shutdown.

    Yeah, that would probably drive me insane. What's the point of electric start if it can't recharge itself without additional electronics? I think I would be very likely to get the parts and fix that issue. I'd also be very likely to replace that solenoid valve with one that operates...

    Predator 9500 Generator backfiring on shutdown.

    Here's your diagram, or at least a Chinesium version. It says for 7 KW, but I doubt seriously there's any difference in the wiring of a 9.5 KW. It's a pretty cheesy drawing, but now it makes what you described a little more recognizable. Still makes no sense, but I can see what you say now...

    Predator 9500 Generator backfiring on shutdown.

    That was probably a bore scope, not oscilloscope. Totally different animal. O-scope is for analyzing electrical signals, much like a volt-ohmmeter, but with a screen to display the waveform of the signal. Extremely handy when troubleshooting electronic devices, but about as useful as a screen...

    Predator 9500 Generator backfires like a shotgun on shutdown

    If you put the meter in series, you better be looking for current, not voltage. A parallel connection(solenoid terminal to ground) is needed for voltage if you also expect the solenoid to operate. Backfire is usually caused by a rich exhaust mix in a hot exhaust pipe or muffler when fresh air...

    Craftsman deck exploding

    It took 18 replies before someone suggested blade balance/installation causing the vibration? Here's a suggestion: Take the deck off the tractor and elevate it, if for no other reason than more comfort. Remove the blades, remove the belt completely, and if possible, remove the blade safety...

    Not getting gas to primer bulb with new bulb and carburetor

    Most larger engines (>3.5 HP) use a tank with gravity feed, or a fuel pump mounted on the side of the engine to pull the fuel out of the tank, and the carburetor has a float that operates a needle valve to maintain fuel level in the 'bowl'. In fact, I haven't seen a modern bowl mounted carb in...

    Much needed maintenance

    I found someone's dead cat tracks on my truck one time. ......

    Much needed maintenance

    Takes a lot more than that to hurt my feelings. I just get amused when folks tell me how to handle 'the juice'. I'm one of those people that likes to be grossly underestimated. That way, I don't disappoint.

    Much needed maintenance

    I seem to be using mine often enough, even through the winter, to keep it charged. Like I said, when I took the battery off the mower, in 15 minutes my charger was showing full charge using 2 amp trickle. I have quite a few water oak trees in my yard, as well as red oak and a few elms. I pick...

    Much needed maintenance

    BTW, finished the oil change tonight. Took forever to drain the oil. Should have warmed the engine up first. Forgot what I put in it last, so just put Castrol GTX 10W30 in it this time. That stuff's great for high temperature air-cooled engines. My old VW had 400 degree head temps, so had...

    Much needed maintenance

    Oh no, I wouldn't. Sometimes I read forums like this just for a good giggle. I'm pretty careful who I try to help, and how I dispense it. I learned my lesson a long time ago about hurting a millennial's feelings.

    Much needed maintenance

    Unless you're using it for a hedge trimmer. Then you have to use the virtual ground.
