Guys, I got my Onan to vibrate!!!! Yeah!!!
Coach battery needed charged. At least I think that is what fixed the no crank problem...
After I got it to crank it would not start at all. Would not even fire at all.
Here is what I did next.
#1 Unplug the fuel line to the carb and run it with start button for 1 minute
to purge old fuel. (fuel I got for the first 20 seconds was yellowish). After that I sprayed Carb cleaner into the fuel line hole on the carb and let it soak for 20 min.
#2 Remove air filter and spray carb cleaner into intake while starting the generator. Let soak 10 min (fuel line still unplugged)
Repeated 10-20 times until Onan ran for about 5 seconds on just the carb cleaner alone (yes it will run off the fumes from the cleaner)
#3 Once it started running for about 5 sec on the carb cleaner. I put put fuel line back on and air filter back in.
#4 On the bottom of the carb bulb there is a screw for the air/fuel ratio (at least i think thats what it is). I screwed it all the way in and tried to start my generator. I backed of the screw 1/2 turn over and over and over until it finally started.
#5 Let it warm up for an hour..... then run AC in coach on low setting for an hour.
You can tweak the carb screw after the gen is warmed up under load if it runs a little rough. My girlfriend likes it a little rough though.
Bye!
