It is time for a new replacement engine.

You are probably trying to run to many things at the same time. Electric water heater, refrigerator, furnace blower, cook range, to many lights.

Briggs has recently upgraded the capacitors to 40 UF, 420V. Try ordering these from Preferred Power.

Check for lack of oil pressure. The low oil pressure cutoff would probably activate if pressure doesn't happen in 5 seconds.

This is absolutely not a gas psi problem. You haven't mentioned if the unit was connected to load or not. That FC5 fault is low frequency and could very well be caused by an overload condition. Take an amperage reading while the problem is occurring. If it is not overloaded then it seems like you may have a problem with your governor control circuit assuming the engine is running ok otherwise. Some basic checks include checking mag p/u voltage (they are generally located directly over the flywheel on aircooled engines and are difficult to see so try to following wiring) while cranking / running generally it should be over 1.5 vdc. Also check for mechanical binding. If the unit never makes 60 hz. also try adjusting the govenor although If the unit did make good frequency at some point you may be having a problem with the controller. If the unit is hunting dramatically then try adjusting whats called your frequency or governor gain setting to a point that's stable.

off you ask them they have it. ask maker of engine, the tool make would not. (sump) service manual is the name. ask maker https://www.briggsandstratton.com/na/en_us/support/manuals/results.html

This appears to be something for a Briggs and Stratton engine, so I moved it from the Microwave Ovens category. 'Make model (what is is)' in all questions please and in this case (what it is off) as well :>D Call Jack's Small engines. If he doesn't have it, or know a replacement, no one does! https://www.jackssmallengines.com/jacks-parts-lookup/manufacturer/briggs-stratton/briggs-stratton-engine/400000-699999-series/407600-to-407699/407677-0258-e1 images of Regulators. Look similar? https://www.google.com/search?q=voltage+regulator+407677-0258-E1 ..

Maybe you can check on operation manual or ask your supplier. If you need to have diesel generator set for power generation, please refer to a company website: www.dieselgeneratortech.com. They have doing genset for more than 43 years.

Doesn't look like anyone came close to answering this question correctly.While I realise I am answering a VERY old post, a correct answer may help others that come here in the future who are experiencing the same problem.The issue is with the starter clutch. It screws onto the crankshaft and works like a ratchet wrench. It allows the crankshaft to turn freely one way but "catches" if turned the oher. Most people don't maintain them properly so it gets rusty inside and the bearings don't move like they are supposed to. Hence the clutch doesn't lock.It's usually a pretty simple fix. Remove the flywheel cover, secure the flywheel so it doesn't turn then use a rubber mallet and a drift to loosen the clutch. It has normal threads so it turns counter clockwise. It should come loose pretty easily. Once off, look at the front of the clutch. There is a cover which is just pressed on. You should be able to get it loose with a hammer and small flat head screwdriver. Carefull you don't loose the bearings (there are 6) which are pretty large. Clean the whole thing out, removing any rust and debris.Then spray the inside with some lite machine oil (don't use grease or any other thick lubricant).The shaft should have a piece of felt in the center of it. This should also be soaked with machine oil. To reassemble; place the washer and shaft back into the housing, then place a bearing in each "hole". Give it another shot of machine oil and press the cap back on.Put it back on the engine and replace the cover. You should now have a workng starter. There is a small hole in the front of the clutch. You should periodicaly squirt some oil into it to keep the clutch lubricated.

hi I think that the problem you have is not with the coil. let me explain : when there is the need to stop the engine simply we push a button or use a lever in both cases what it simply does the coil is grounded to earth this stops the spark supply to the spark plugs . find the cable which connect from the switch on to the coil because this cable intermits to short to earth stopping the spark going to the spark plug ( replace cable this will prevent the engine to stopping )
