We've be static for awhile and I failed to exercise the Onan 5.5 Marquis Gold. It would not start. Found a series of excellent You Tubes on RV maintenance by Mr. Don McAdams including one on diagnosing my problem CLICKY.
I did what he said and Sea Foamed it a lot. It got it to where it would start but then ran real rough with lots of smoke and no amout of Sea Foam made it any better. He and others (including Onan) say the only solution is to replace the carb. Rebuild is dangerous and I didn't want to take the chance. (Someone will post soon and say they did it and everything is fine. Good for them. The Gen is in a compartment under my bed and I didn't want to take the chance.)
Found a brand new one for $233 on Ebay. Watched the video and did a very simple change out. Onan purrs like a kitten.
Offered as a lesson learned. I've got computer reminders to run it under load every two weeks.
I am somewhat curious on your situation. You did not say how old your rig is, nor did you say how long you failed to run your generator. I'd be curious to know both details.
