Trouble starting Honda generator
I have a Honda EB3000C generator with a Honda GX200 motor. It's only
a couple of years old and has very low hours. I decided to drain the fuel and refill with fresh fuel. It had sat for about a year. It wouldn't start at first but I sprayed a shot of Gumout into the carb bore and it started on the next pull. So I let it run for about 10 minutes and it ran beautifully. I decided to drain the carb so I siphoned out must of the fuel in the tank, restarted the motor and shut the fuel supply valve off. It ran for about three additional minutes but instead of stumbling and dying like I expected it started to backfire very loudly so I quickly turned it off. I thought maybe some water had gotten into the fuel so I drained the sediment cup and the carb bowl. I put some fresh fuel in the tank and tried to restart it. It would start and run maybe 2 seconds, then backfire and die. Thinking there still may be some water in the carb I redrained the sediment cup and the carb bowl and tried to restart. Same thing, run, backfire and die. I added a little Heet to the fuel, repeat drain and restart - same thing. I'm thinking the original backfire episode may have damaged something but before I tear into it further I thought I'd solicit any experience anyone might have with a similar problem. Thanks in advance. |

Thanks in advance. 1.) Loosen the fuel tank cap a turn or so or 2.) Remove the air filter Will it then run? 3.) Pull the spark plug out and check for fouling Clean the plug with a wire brush, emery cloth.... Will it then run? Simple things first. Even check for a stuck choke. |

Trouble starting Honda generator
The only time I've known of a Honda giving trouble, was old
gas. Some ether sprayed on the air filter did the trick, and it ran fine after that, with the old gas. Since the wildcard is the carb service. Please consider pull the float bowl off, and see if the metering jet is clogged. My old Toro snow blower had some particles of black floating in the gas. It repeatedly clogged the metering jet, until I installed a fuel filter. I was very fortunate to have a fuel filter on hand. -- Christopher A. Young Learn more about Jesus www.lds.org ..

Thanks in advance. Backfire is usualy ignition related as in timing or the ignition module failing or a sticking valve, you might pull the plug and ground it then have some one pull the starter to see if its a weak spark indicating the module. Sears has a 4$ inductive spark tester , it looks like a writing pen you touch it to the plug wire when its running it should show if its electrical by the missed firirng pattern. A compression test might or might not reveal a bad valve. Misfire-backfire was my ignition module and coil on several other motors, I dont think its fuel related, on lawnmowers after you hit a rock and stall it the timing can shift and cause missfiring, but a gen cant be stalled like that. New engine oil like mobil 1 , and spray in and kill the running motor with Fogging oil might free it up if its a valve. That 4$ sears tester will pay for itself on future plug, coil, wire issues on any motor, it just save me 250 on my car, a guy wanted to replace what was not wrong, it was one 40$ coil. |

Did it have fuel stabilizer in it while it was sitting for a year?
Even if it did, my first suspicion would be that the carb is fouled. But usually that doesn't lead to backfiring, just not starting. On the other hand, the backfiring did start when you turned off the gas. If it was timing related, a valve, etc, curious that it started just when fuel was shut off. I suppose the float could be stuck open flooding it badly. After checking the spark plug condition and for spark, I'd pull the carb and rebuild it. If you get a service manual it should be fairly easy. By taking it apart, you can completely clean it and remove any gunk. The rebuild kits are cheap, look on Ebay. I got one for a Tecumseh engine for ~$12. |

A few pushes on the bottom and the plug was clean. Then re-gap the plug and install for more miles. Eventually you had to replace the plugs, though. |

Naaah, we all use wire brushes, now. Works fine, for me.

Thanks in advance. Like others have said, change the plug first just to be sure. Unlike what others have said, lean mixture can create a backfire condition. The generators that I have worked on that have sat for a year and wouldn't start is almost 95% due to dirty carbs. The carb has to be disassembled completely and EVERY passage clean. On a Honda, you'll most likely need to get a small wire and run it thru the pilot jet after removing the jet. Also, drain all gas out of tank, check for rust. It will be a waste of time to clean the carb is the tank is rusty. Hank |

So, check the carb, check the timing, check the valves. -- LSFT Drive a little slower than the posted speed....... And you too can become a fracking prick. |

Never, ever use starting fluid (or ether) on a gasoline engine!!
It WILL damage the engine to some extent, and it is very flamable. Do NOT use the stupid mormons advice about this!! |

The biggest problem w/ gasoline engines is the possibility of the high detonation pressures that they're not designed for.

To the extent that the connecting rod is sticking out the side of the crankcase, for one. An engine in perfect working order does not need starting fluid. If you need starting fluid to get it running, it has MAJOR problems. If you're forced to use it, it only takes a whiff to make a huge difference. Idiots will unload an entire can of the stuff into the engine. Old diesels will make one heck of a clatter when they fire after a shot of ether. |

Inasmuch as "Starter Fluid" is sold at the auto-parts store, I can't imagine there are that many cars that are powered by a clockwork mechanism where the pendulum is difficult to get going... Hmm, an auto parts store sells it, therefore it must be okay to use on your car... Extra points for use of 3rd grade logic. If a car is so difficult to get going that you NEED starter fluid, it's very very close to death. |

Trouble starting Honda generator
Years ago, I know a fellow who sprayed ether into the spark
plug hole (my Dad's next door neighbor, trying to help my Dad get his generator started.) Sadly, the generator piston locked up. Dad bought another generator, and gave me the old one. I broke it free with a big wrench on the flywheel nut. Then, it started, ran for half a second, and threw a piston rod and broke a hole thorugh the crankcase wall. I learned to relube the cylinder wall by squirt in some two stroke oil when a cylinder wall is dried by ether. I also learned that spraying some ether on the air filter will help balky generators start. I've done that several times since then. -- Christopher A. Young Learn more about Jesus www.lds.org ..

Thanks in advance. did you ever get this fixed? Lean backfire on shutdown is VERY common and totally normal, particularly on a C.A.R.B. compliant motor. But obviously failure to ever re-start and run again is not..... It's an old and mostly irrelevant thread, but given the description and symptoms, sounds like some gunk from old fuel has fouled the carb or other part of the fuel system. The poster implied that it had old fuel in it. The carb may need to be disassembled and cleaned, they have cheap rebuild kits available for common engines for ~$10 or less. Or a new carb, there are chinese aftermarket ones for common engines that work. |
