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.
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.
