Engine won't run smooth for longer than 5-7 mintues

Kohler 12 hp new on lincoln gen/welder (27 hrs on unit) starts good runs very smooth then 5minutes of running drop down in rpm to almost nothing then will pick and good for another 5 mintues then does the same thing. Does this under load or no load high idle or auto no differance.

    Choke was not on. I was running under load as a gen. (20-25 amp) when this started.

Changed filter, oil, full of gas checked gas flow everything is good , when I start m lawn mower it runs , when I engage my pto and start mowing for about 5 minutes it just quits


if this is got the 27 hp kohler engine, I know exactly whats wrong with it , due to grass and engine oil building up in a short time under cylinder heads , it actually makes a tight ball of grass and stuff there !! this holds the engine heat and ruins the ign module that's just above it there , I put two on in one season ( tractor runs 6-10 hrs day 6 days a week ) I finally gave up I bought a Kawasaki 27 hp twin and installed it , now its run for two seasons and no problems
engaging the pto has nothing to do with it , it would cut off if you just drove it around for 15 minutes

I have a Lincoln Ranger 8 with an Onan Engine. When started the engine runs at an EXTREME RPM. What causes this?


Check movement of the governor arm without it running. You should be able to move it by hand. If it is stuck, it could be the idle solenoid, or possibly something else more major.

Miller trailblazer 275 stalls after about two hours of welding.....


there is a voltage regulator directly above the electric fuel pump on this welder, make sure the three connectors are making good contact, there are three wires attached to it, the center conductor is either violet or blue, if the spade terminals are not making proper contact your machine will shut down as you state
you may also have a "sticking" or faulty fuel stop solenoid
if after you remove and check the connectors at the voltage regulator, the problem persists, locate the local Kohler dealer, your engine has a 3 year warranty for parts and labor

My welder revs up but wont put out full power


We need a better description of what is happening. I see many engine driven welders that when loaded up heavily the engine rpm drops because of needing a tune up or complete engine overhaul. Since the engine can't run at designed r.p.m. the welder won't put out "full power" With a better description of problem, Such as engine is not slowing down but will only weld at 100 amps experts here could help you better.

My 3.5 kw kohler marine gen starts and shuts right off throwing code uu (under voltage) last season it did this and sometimes showed loc (loss of coolant) but never appeared low or showed sign of coolant...


Check that when you run it, it is not in fact making correct voltage (within about 10% is good), also make sure the engine is coming up to full speed, 3600 or 1800. You could check this with a multimeter that measure hertz. On the main output leads when the genset is running make sure it is getting close to 60 hz. or if you are in an area that uses 50 hz. check for that respectively. There are a couple things that would affect this, one would be your SCR module. There is a test procedure for this which you could find here. http://www.scribd.com/doc/50171916/tp6196-1 . I don't work on marine units, mostly standby so these manuals are for residential. Check your fuses, could even go as far as checking the wiring in the back and wiring and condition of the brushes and sliprings. These actually build field voltage to make 240 or 120 volts whatever your unit is configured to make. The brushes need to sit flat on the slip rings and on a unit with 10 hrs. the sliprings I can't imagine would be very dirty but check that as well. If you have an ADC2100 controller use this manual to go into the controller to verify that it is set for the correct voltage that the machine is built to make. The only other fairly simple thing to check that I've had issues with is if Kohler mounted a fuse block on the side of the cabinet mounted to the genset with no vibration isolation. Check these fuses while attempting to run the unit and make sure you getting steady voltage out of them as sometimes they will vibrate causing pulsed voltage to come out of them and can give you an intermittent UU, UF, or OC fault (undervoltage, underfrequency, overcrank).

My gen starts and runs for 1 min or so then dies restarts then dies again and again. if i start it under load ( turn on air con) it will run for 10 min then die allen


Is there a fault?? All UL listed generators including Kohler are required to lockout on a fault on shut down. This really sounds like a problem with your 2-wire auto start connection between your automatic transfer switch and genset. RDT model automatic transfer switch it is the 2 middle wires on the green connector and terminals 3&4 in the generator. close to run and open to shut down. Any open at any time will cause the unit to shut down. The 12 will shut down instantly upon an open because your 5 minute cool down is built into the transfer switch.
