bobar Posted September 27, 2012 Share Posted September 27, 2012 Onan micro2800 generator cleaned carb will only run at slow speed if I try to power anything up it will die. I have checked filters had very little trash in them any suggestions. Quote Link to comment Share on other sites More sharing options...
Davidadro Posted September 27, 2012 Share Posted September 27, 2012 I think there is an idle spring connected from the throttle to a load sensor that increases RPM when under loads. I would check to see it that spring or lever is connected properly or to the proper place. Sorry, other than that, I am clueless. I am sure there are many possibilities, but that is the only one I could give any experience on to. Good luck my friend! Quote Link to comment Share on other sites More sharing options...

90toydolphin Posted September 28, 2012 Share Posted September 28, 2012 i could be wrong, but i think that is also called a governor? if it is the same my experience has been they are not easy to adjust properly and if set wrong can allow the engine to over rev and "burn" itself up. i have a honda motor that the spring has gotten weak, bent the spring a tiny bit making it a little stronger again. been to lazy to try to find a replacement spring and it has worked for two years now ) Quote Link to comment Share on other sites More sharing options...
WME Posted September 28, 2012 Share Posted September 28, 2012 Check fuel pressure with the engine running should be in the 4lb range. Try running with the gas tank cap removed. A vacuum in the tank will reduce fuel to the engine Quote Link to comment Share on other sites More sharing options...
