SOURCE: ENGINE OVER SPEEDS WHILE RUNNING

This is almost surely a problem with the governor, check it like this.
Have someone with a finger on the kill switch.
Watch the governor arm while starting the engine, if it does not move almost immediately after starting the engine it is broken.
This is not a simple repair as it involves taking the crankcase apart, you'll have to contact robin/subaru to get a parts list in order to get the right governor spool and weights.
For an experienced technician this is about a 2 hour repair task.

Hope this helped,
Carl

SOURCE: I have a Honda generator model EM3500X with auto

The control board that senses load (current) is not working.It should drop to low with no output current. (nothing running)

Check your air filter to make sure it is clean, especially if the gen. has been run in dirty, dusty conditions. Make sure the gas tank vent is not clogged.

Also, pour some combustion cleaner into the carb. through the air intake to clean the carb. It sounds like it is starving for gas.

Hope this helps.

How do I get a powermate 8hp brigs and Stratton generator to idle. I bought it and it wouldn't start. I cleaned the carb and it started on 1st pull, now it won't idle it run wide open all the time.


You have jet clogged, or still some obstruction in the carb. Hopefully you have a good inline filter .I'd take it back apart all the Jets and seats & Chem soak or a cheap complete rebuild.

I HAVE A POWERMATE 5000 THAT SHUTS DOWN UNDER LARGE LOAD . I THINK I NEED AN IDLE CONTROL MODULE.THERE IS A 2 WIRE MODULE IN THE START CKT. #21009XA IS THIS IT AND WHERE DO I GET ONE .


Idle control comes into play when there is no power draw forcing the engine to idle with an electro magent. If you feel that the electro magnet is interfering with governor, temp remove the wire to the solenoid. Usually the idle control will not effect how the engine /gen output power. An overloaded condition will cause the engine the go the full throttle as the internal governor of the engine will try to maintain 3600 rpm. Overloaded condition will greatly shorten the life of the generator/engine. Try to use only about 80 % of rated power. Large motors can draw three times running amps. A compressor using 12 to 18 amps to run can draw over 40 amps to start.
If your generator could handle the load in the past, check the engine for loss of power, or the generator for faulty voltage regulator or capacitors out of range. Easy to check. Connect digital volt meter to plug /load and look at volt reading while running with no load and loaded. Voltage should stay between 110 to 120 under load and with no load (unless goes into idle mode). Good luck

It runs wide open all the time im wondering where idler arm setting is at


It sounds like the govenor spring has become disconnected or the clamp on the governor shaft has become loose and allowed the linkage to get out of adjustment. If problem has occurred suddenly it could mean the governor gear assembly inside the engine has broken and means the engine will need to be dismantrel to replace the governor gear assembly.
Check throttle linkage to see if spring is attached at both ends, one end on the throttle linkage and the other at the fixed point on the engine or to the end of the speed control lever. With engine stopped the spring should hold the throttle wide open and hand pressure on the linkage shoud be all that is needed to move throttle shaft closed to the idle position with no binding in the movement of the linkage.
If spring is OK and while engine is running, linkage should be able to be be moved to bring engine back to idle. If porblem has occurred gradually, then linkage will need re-adjusting. Loosen adjusting clamp on governor shaft, then holding linkage in wide open throttle position rotate shaft as far as it will go in the opposite direction to that requred to close throttle to idle . Re-tighten clamp.

I have a briggs & stratton / Powermate portable generator; there is a lever with a black plastic handle on the end of it, right next to the 'choke - run' lever which has a red plastic tip on it. ...


The engine on your generator is also used for other applications some of which require an adjustable  throttle control. On a generator the engine must turn about 3600 rpm to obtain proper output of voltage and cycles. Upon further inspection of your throttle/governor you will probably find an adjustment consisting of a screw, nut or a tab on one end of the governor spring that can be reset for proper engine speed. (tab can be bent for more or less tension on spring) To check present governor setting, use a volt meter that has frequency setting. Make sure that generator is set to about 60 hz. (3600rpm) Good luck with your generator.

Wont speed up


If it is suppose to speed up there should be a switch that says auto idle. Just turn that off and this will cure your problems

I've never been a big fan of the 180 OH family of engines in these things, but here goes.
1 - If the engine will stay running while it surges, close the choke a little at a time and see if it settles down. If it does, there is something amiss in the carb. The carbs on these engines are very picky about tiny bits of dirt. The good news is that they are fairly simple to take apart and clean, the bad news is that lots of the parts are plastic and break easily. At least they aren't too expensive.

2 - I've seen 2 ways to adjust the governed speed on these engines; a spring that connects to the governor arm at one end and a tab bent up from the sheet metal that mounts on top of the engine at the other - bend the tab so the spring is tighter to speed the engine up, and (b) a jam nut and screw mechanism that presses against a lever that pulls on a spring that connects to the governor arm - screw the screw in tighter to raise the engine speed.
Note that in either case the mechanism adjusts the tension in a spring that pulls against the governor arm, this is helpful in finding out where to make the adjustment.
Here in the US we want our 2 pole generators like this to run at 3750 rpm at no load so that we get very close to 3600 rpm at load. If you're using a DMM to measure the output of the generator in Hz, you want 61.5 at no load.

If nothing you can do with the choke makes the surge go away, you might have a misadjusted governor. The Tecumseh service manual has a great procedure for making this adjustment, essentially what you do is loosen the retaining nut on the governor arm, twist the governor shaft to its minimum speed position, then hold the throttle assembly at the idle stop and tighten the governor arm jam nut. Always keep a finger near the kill switch when running the engine the first time after this procedure, it's easy to mess up and have a runaway engine.

Please rank me if this was helpful,
Carl
