Or am I still having the same issue?Re: Honda EU2000I Not starting at higher altitudeTried it last night and it did start with the choke off. Does the temp make a difference? It was 110 yesterday and still warm at night. Or is there something wrong with the float or maybe something stuff in it?Re: Honda EU2000I Not starting at higher altitudeSo I followed the tutorial on this forum and cleaned the carb out....It will not start when the choke is off now. But when I try to start it with the choke on it starts first pull. So it may be good to go now. There was some dirt/rust in the float bowl. Also some white chunks and powder....almost looked like calcium. Thanks for everyone's help.Re: Honda EU2000I Not starting at higher altitudeAir filter is really clean.Re: Honda EU2000I Not starting at higher altitude Kayteg1 wrote: aaarneson wrote: Kayteg1 wrote: aaarneson wrote: I live in Phoenix and my generator starts up really good with no choke. That is not normal that engine starts easy with no choke. I think for some reason your carburetors run rich and higher elevation magnify the issue. Pull the plug and check the color. Just replaced the plug....the previous one was pretty blackened. 2nd indication you have rich mixture. Beside jet, that might be high level in fuel bowl and dirty air filter. I will check air filter but how do i know there is too much fuel in bowl? Also I currently have premium fuel with some seafoam in there...would that help it start without choke?Re: Honda EU2000I Not starting at higher altitude Kayteg1 wrote: aaarneson wrote: I live in Phoenix and my generator starts up really good with no choke.

Was in Dolores, CO over the weekend and could not get it to start at all. Used premium gas, no choke then choke....still no start. I also added a little sea foam. Nothing. Go back home and it started right up. Was going to pull the carb and give it a cleaning...but could this issue be something else. Do I need a new main jet for higher altitude? I seen lots of people with this generator with the stock jet run fine in higher altitude. Thanks for the help.
