Why honda generator wont start eu30


First, see if there is fire to the spark plug. If not, then that is the problem. If there is fire, try a shot of starting fluid in the carb. If it starts initially, then most likely the jets on the carbureator are clogged. You should remove the carb and clean/rebuild it.

Generator back firing from inlet manafold


Your symptoms are from running lean. Foam air filters put debris in carb jets. Check all the carb passageways and jets. Always start with a new plug.

Wont start


Make sure you have new fresh fuel in the tank; Check to see if spark plug is firing; if not , check the coil. If all of the above checks out ok, the carb might need cleaning. Have you checked all switches ? Any loose wires?

Troy bilt 5550 generator no start please help


fuel, fire, mechanical. Miss one and she won;t run. Are you sure the gas was good? Not some old can laying around that may have turned or become water contaminated? If it was fresh gas, then take off the air cleaner and spray a little wd-40, or ether, or brake cleaner whatever is flammable into the carb throat. Just a 1 second shot is all it should need. Try and start with that. If it starts and then dies quickly, still a fuel problem. maybe a gasket is damaged, or the jet is clogged. When you said you checked for fire, you acutally took the plug out and had it grounded while spinning the motor and saw spark? If you saw a hot spark then you have eliminated fire. Mechanical not likely if it was running well a short time before. If a valve was damaged, it would still run but not too well. My gut feeling is it is related to fuel.

Our onan generator ran out of gas. we refueled but the generator will not start. i gave it a shoot of starting fluid, the generator fired and run for a second, then died. could it be a cogged fuel filter?...


No, not the filter, you will need to try to prime the carb better then with starting fluid, pour some gasoline down the carb, you may have to do this a few times, but everything will fire back up again once you get the air out of the system

My 5700 runs about 5 min. then back fire out the carb and then wont start for about 10 min. then it starts and run about 5 min. and stop agin i clean the carb check the valves


I would first said that your intake valve is not sealing like it should (burned, warped, etc). But, you have already checked that.

The other reason for a backfire is timing. Could your magneto or keyway be heating up and moving throwing off the timing? And speaking of keyways, how does the woodruff key look? Is it chewed up or distorted?

Wont stay running


the problems is in the carburetor, common problems when unit does not run often and rust get get build up. get some automotive carburetor cleaners and spray it heavy in the carb, don't worried about flooding it or damaging anything, it will dry out faster than gas. (use little gas if you need to) try to start it up and get it running with the carb cover off and continue to spray carb cleaner in the carb while the engine is running, do this couple of time and hope that would clear it out. if that don't work you will need to take it apart and clean it. you have small tiny object obstructing the carb flow. the unit doesn't have a fuel pump, it run on gravity feed, the carb are easily obstructed. hope that help a bit

Gen. wont start been stored since 03 bought new used twice


As for checking for a spark, remove the plug from the engine, plug in to lead, then rest it somewhere convenient, with the threaded end to ground. (ie touching the chassis or frame)
The low oil indicator may be on the side of the engine, but I'm not certain.
If you discover that the spark is good, it could be a timing problem.
If there is no spark, it's probably the magneto.
I hope that helps.

Coleman6250 Generator PM0545007 - Won't start/run. Can get it sputering with starting fluid, however, not a "pop" on gas. New gas, blew out line & carb but still think no gas getting thru carb. Plug...


Most gasoline engines need three basic things to run: proper air/fuel mixture, sufficient compression, and a properly timed spark. Check the easiest, cheapest things first, then check the "Gee, I forgot to turn on the gas" kind of things next, then work your way onwards from there.

Compression can be guesstimated with the proverbial thumb-over-the-empty-spark-plug-hole routine as you turn it over casually to check compression. If it doesn't blow your thumb out of position, you could have a hole in the piston (overheating response) or a stuck or damaged intake or exhaust valve.

Check for fuel flow by carefully disconnecting the fuel line to the carburetor and letting some run into a tin can (no styrofoam coffee cups, please). It should dribble freely. If not, you have to back-track the line and find out where the blockage is.

Spark is one that sounds like you've already tested (spark plug out of the cylinder head, hooked up and laying on the metal engine as you turn it over?) so check timing. You will probably need a manual for this test, although a good estimate is that the plug should fire just a wee bit before Top Dead Center position of the piston. Like I said, a manual comes in handy here.

From what you've mentioned, though, I'd start trouble-shooting at the fuel flow part first.

Good luck,

GRB
