Predator 4375 no start

[hardcore302]

I notice that the fuel is leaking from the fuel shutoff. I will replace this. Also will replace plug. But these alone shouldn't result in a no start, correct? I mean completely dead. I've watched a few videos where they replace the carb and it comes back to life. This generator has maybe 10 hours max on it. Got it new. Thoughts? Thanks.

Did it sit with fuel in it? If so, the carburetor jet could be clogged up. You really want to run generators out of fuel using the fuel shut off when they are going to sit for any length of time.

Also does it have spark? The Predator engines come with Chinese "Torch" spark plugs which are notorious for failing. So notorious in fact, that when I do a re-power on a piece of a equipment with a Predator engine I replace the Torch with an NGK plug right from the start.

Yes sat with fuel. It has an ngk in it now. I guess a new carb is in order huh

If you want to confirm a fuel delivery/carb issue, take the air cleaner off and spray a bit of starting fluid down the carb throat and try to start it. If it fires up and runs for a second or two, everything else is fine, carb jet and/or emulsion tube need a clean.

Like lawnman23 said, try starting fluid to see if it will run, then address the fuel situation if it does. I've had so many chinese fuel shut offs fail, leak and fall apart that I either bypass them on my own stuff, or I leave them intact and never touch them.

If you do order a replacement carb, hang on to your OEM to clean/rebuild and keep as a spare. Throw it in the box that replacement came in.

Another vote for using starting fluid or carburetor cleaner. Take the air cleaner off, open the throttle valve, and douse it with carb cleaner. I use Seafoam, Amsoil Powerfoam or Berryman's B12 personally. Douse it really well and then try to start it. Once you get it running, let it run for a while (putting a load on the generator would be a good idea), like at least 15 minutes or so, turn the fuel shutoff valve OFF while running (assuming that the shutoff valve is working) and let the engine quit by itself after burning the fuel in the carb. Then I would strongly recommend removing the fuel from the tank by disconnecting the shutoff valve from the line to the carb and then opening it into a container. After that, of course reconnect the shutoff valve to the carb line.

Since this is a generator I'm assuming you use only in emergency situations when the power goes out, this should keep it honest enough to fire up when you need it (after putting fresh fuel into the tank and opening the shutoff valve). I have a Honda EU2000 generator and I never store it with fuel in it. I always drain the fuel out of the carb and then siphon out the fuel from the tank. It's always worked when I've needed it (so far).

Also, I've heard these Letayar fuel shutoff valves at the link below are good if the one that came with your unit gives up the ghost:

My local lawnmower repair guy gave me a couple of tips that really helped. On some models the jet has two holes a few have three. He uses a welder tip cleaner tool to poke through the carb jets. I wouldn't replace the carburetor yet.

I learned my lesson 9 yrs ago when I had some gas powered items in storage while I was building this house.
Carb kits are expensive and more often than not a new carb can be bought on Amazon for less than a carb kit locally. Look for the markings on the old carb for matching new ones.
I now run only E0 in my small engines with a splash of my home brew Seafoam and if I am not using it regularly it gets the fuel drained, some 2 stroke oil added and then run until it sputters and dies.
