Fault code 14 is for over frequency. So what that means you have too much voltage and frequency output from the generator. Most things run off 60hz. The screw you turned is the speed screw. To keep it simple it adjusts the speed of the engine and that lowers the amount of voltage and frequency output from the generator.
THIS IS HOW I FIXED MINE, IN THE CASE OF.... "I CAN'T START MY GENERATOR" It's has been two years since last time it was running, so I started by checking oil level full at gen (it won't start if low oil becouse of sensores), gasoline more than 1\4 tank in the RV (also safety censors), sparkplug checked for good spark, check the manual circuit braker ( to be ON) at front motorhome engine compartment for 12v current to the gen to be able to start it, also cleaned the carburetor and even installed new one but same situation, then checked wires and found some has been chewed by rats so I replaced them, by this time it started but stay running only by keep pushing the switch on all the time, so I knew it was electrical problem from the engine itself, so I took the generator out from my RV to work in my garage, ( I did this by myself with some tools and old Mayan tricks ) lol, it's really heavy for one person. I disassemble the unit at my garage and started by removing the cover, then the cooling fan or flywheel unit (it's 2 items in one unit) until finally I was at the gen rotor and brushes assembly area and this is what I found: one more wire chewed by filthy rats plus the stinky rat nest in the middle of the generator motor coil, I fixed the wire and sanded the commutator copper contacts where the brushes are sitting becouse they were real duty with old urine from the rats, and of course I got rid off the stinky nest, lol!!! Then I assembled everything back together and bingo it's runing like a champion. For this project materials involved was about $60.00 including an aftermarket new carburetor and an harmonic balancer/steering wheel puller (available at any auto parts for $25.00) to pull the aluminum fan out and (flywheel). Just picture this: (Any gasoline engine run smooth if gasoline and DC current aren't interrupted) so following this important principle you'll always find the problem to be fixed. Also if you have a onan microlite 4000 like mine, don't run it for more than a minute without the cover becouse you'll cook the engine real fast, also keep the eye on the aluminium fan and your fingers after cranking it in case you missing one or two members...just kidding, lol!!! After testing the gen then put the air cooling assembly back and the rest of components including the cover, now it's ready to be installed at your RV. Once the gen it's installed back at your motorhome or RV start your gen to be tested for electric power but don't forget to flip the electric switch (on) at the gen electric panel (sometimes hiding under or around the electric controls) to transfer power to your RV GFCI main outlet and electric panel as well, if your it's equipped with GFCI reset it and tested for green led light indicating power is ready at you main breakers panel, flip your main switch (on) along the others ones at this moment if you still don't have power then it's a faulty main braker, flipping it many time sometimes make it work again, mine did it, lol!!! If yours didn't buy a new main breaker. If this can help eaven one person save time and $$$ it'll make me more happy, thanks for reading!!!
Omg!!!! I have the same issue! It runs like sh!t if I hold the start button but dies after releasing. I’ve replaced, carb, fuel filter, spark plug, air filter, oil, starter. I’m going to try that! That’s for the info!
Thx every piece of info on these generators helps. Mine runs for 5 or 10 then stalls. Replaced fuel filter and am about to replace carb. But will try your fix first.
Any luck? I have the same same problem and mine has a new fuel pump and filter .. I can keep min running if hold and or move the moving throttle things on top
I'm beginning the journey on my pos. Make sure you camp where there is electric, or your screwed. First thing I did was replace junk rv battery with 2x heavy duty deep cycles. Now I can crank it mant times till I say F it. I'll let you know what I find, like the idea, if remove from chassis to fix.
Turning clock wise will increase the engine RPM thus will increase the volt and frequency, you have turn it slowly and monitor the volt and frequency using a multimeter which read Hz.
I did this and it worked. I messed around with both screws until i got it to run. My only issue that i have right now is that once i turn on the AC or Mircowave it knocks out the generator :(

Is clock wise to speed up or slow down the generator?

Thank you
I'm glad you took the time to read my long explanation, if you can shear your generator experience will be cool!!!
YOU, Sir..... Have just fixed my problem!!!!
Thanks for the info and help mate
THANK YOU!!!! This fixed my 36 code.
Thanks for the video. I have a different issue but, next week it may be the same as yours. Thanks again!

Thanks for sharing. Ill try this out.
That screw is to adjust the governor (hz) so you will not have over frequency or under frequency
Cool, what way do turn screw to lower? freq.
Turning clock wise will increase the engine RPM thus will increase the volt and frequency, you have turn it slowly and monitor the volt and frequency using a multimeter which read Hz.
thank you
@@azizaviation
@@azizaviationthank you
Gonna try this weekend. Sound promising!
How come it looks like a gap between the carb and the manifold?
At minute 3:24 he says he tried it both ways. What does that have to do with the generator?
I did this and it worked. I messed around with both screws until i got it to run. My only issue that i have right now is that once i turn on the AC or Mircowave it knocks out the generator :(
Did you fixed that? Same issue here 😢
For what direction you moved the screws?
It would " Kill " ? What did it attempt to murder ? Ohhhh You mean it would DIE . !
Jr.. ever hear of a 'Kill switch'? that's right, you better stand back
Does anyone know how many turns from the factory? To start out from all the way in
prime it but wont start
