Remove the exhaust. It gets a lot of carbon buildup because the specified mixture is to much. Run it at 100:1 and clean and inspect exhaust muffler and port.
Yes, what you need to do is completely take apart the carburetor and clean it thoroughly (main jet, pilot jet, needle valve seat, etc.). Most people fail to clear those tiny little holes barely visible inside the throttle body; best way to achieve this is to take the finest wire brush you can find, pull a strand out and use a pair of needle nose pliers to maneuver the wire into all the holes. Before you remove the idle mixture screw you must make note of how many turns it takes to completely close it off, that way you can put it back where it was. Before reassembly you have to flush all fuel passages with carburetor cleaner and make sure the fluid is coming out of those holes. I own 12 of these (a mix of EX350's and EX500's)
@@1rdnck Hi. Thanks! You are absolutely right: I missed to see the tiny hole in a pilot jet. Cleaned it with tiny brush. Now it works as it should. Whith your rich experience with these generators what kind of proportion do you use between oil and fuel: 1:50 or 1:100? Thanks!
@@andriikolesnyk279 Honda changed the mixture from the original 50:1 to 100:1; the newer EX500 never had 50:1 specified. I have never even considered 50:1 as it is too much oil for this application, it kills the muffler, the spark plug and the combustion chamber.
Thanks so much for this video. For the first time, I could not start my EX 350 this summer. I followed your video (just a bit fast!), took apart the carburetor and thoroughly cleaned all of the jets. The one part I didn't know about was the carburetor drain valve (through the hose at the bottom of the carburetor bowl) - and left it a little loose on starting the first time - resulting in a gas leak). Once I closed the drain plug - the generator has been running like a charm. Nice steady speed, easy start. Thanks a ton! This is a great little generator for keeping my trailer battery topped off if I don't have enough sun to charge through solar. I don't think you can buy these new any more. It's a shame since they are such great little generators.
Nice. I have one that I found in my grandfather’s shed. Mint, still in the original box. Going to clean it up and get it running
Good video, a little audio would be nice.

I have the same generator. It's better to run a 1:25 mixture and clean the exhaust than to change the engine.
I've problem removing the rotor off my ex350 how can I get it off
100:1 is way way too lean that's like zero oil
@@andriikolesnyk279 1:50 maybe?
Respect 🤝
Hi! I have the same generator. RPMs are floating like in yours. Is there any chance to get stable PRMs?

Keep Up The Work
How much gasoline consumes per hour?
voltage muy inestable.... funciona para equipos a resistencia que no requieran de energía estable, teléfonos, pc, camaras etc.....
Can someone show me how to teardown my ex350 generator
Wht fuel do u use fr it petrol or diesel
Gasoline
This video is too fast and frantic for me but thanks all the same.
Agreed, just click the "settings" button and change playback speed to 0.5x so it plays at half the speed
I wish my brain could do this....
Khói quá
