****, I know this has been discussed in the past. I've read most that I have found but......
Onan RV QG 5500... it sat over a year. It cranks when start button is pushed. What I've done:
New plugs. Confirmed fuel pump is working. Primed bowl and checked fuel by draining it from bottom of the bowl, it's clean. Tried carb cleaner. Tried compressed air to clear any debris. Fully charged batteries and made sure connections are clean and tight. Air filter is new and clean. Oil is clean and topped off.
Now, when I try starting fluid it starts right up and runs till the starting fluid is gone, but it will not start otherwise. It just cranks.
It has just over 100 hours on it.
Any other ideas??? Thanks so much!
