I thought he was putting a new honda 13hp engine on it for me, I was charged over $1,300, and they kept my old honda engine, and put this 13HP Greyhound engine on it that looks like a honda kinda, just blue, but it will start, and stop, over and over again?
Sorry, your optional info doesn't show up right away and I didn't have it on the screen when I asked about it being a Honda.
Personally, if someone charged me $1300 for a $300 engine I would have a serious problem with them.
The Greyhound is simply a Honda clone made in China. Many, many different label names are XXXXX XXXXX them, but they're all the same engine with a few different levels of machining done. This is the Harbor Freight version and is okay, but is nowhere near a Honda.
The first thing I would try is overfilling the oil a little bit. These don't have the best electrics in the world and often the low-oil switch malfunctions.
Quite honestly, I wouldn't spend a dime on this engine. It's not that they're not decent engines, for the money they are. But this should be under warranty and this is certainly a warranty issue. If you do try to do much work on it, you will violate the warranty.
If you do decide you'd like to work on it and you try overfilling the oil a little bit with no success, then let me know and we'll figure it out. Thanks, PK.
You can unhook the oil sensor, you might have to jumper it, but I don't think so, and try it like that. I'm not 100% sure which style sensor they used in that engine. I believe that you have to completely disassemble the engine to replace it as you would with a Honda.
So unplugging the sensor is where I would start. You can also try using a different weight of oil. 10W30 Castrol is probably the best bet. If this engine has a fuel pump, it'll be a round device, probably right beside the carburetor and under the air filter box, it could also be at fault. And there could be something as simple as a loose wire so be sure to check it over for that.
If you had a GX Honda engine of the same size, then it's really a straight bolt-on swap. The Honda engine, a GX390, would run around $800-900 depending on the options. I regularly receive ads for the Chinese engines for $275-325 in this size.
