Fuel Tank is Full, fuel lines are not dry rotted, Only code (which is not a code according to manual) is 3-3
I ran it for about 12 minutes...It surged and stalled the code looks like 3 blinks pause 6 blinks
No auto gen start (I don't think)...Runnin the gen with load (roof air on)... Have same problem w/o load.
It ran for 18 minutes (no load) it surged and quit
All I can tell you is something other than the gen is shutting it down, that is what a code 36 means..I have seen the dip tube that goes into the fuel tank get rusted out(water) and then the gen sucks air and shuts down. Since you describe to me that the gen stumbles before it shuts down I believe it is a fuel problem, how long ago was the carb replaced? Because the shut off is on the carb and I saw this the other day, the shut off was the problem, but in this case it shut down like someone hit the stop switch...worth a look..
