OK Forum Fans, here is the update and conclusion
Update, dropped the tank and found that a critter ( read mouse ) chewed through the elbow gas line fitting above the gas tank. Also found another spot on the gas line had been chewed.
Conclusion, new fitting and gas line and generator runs fine.
Lessons, all critters love to chew on stuff! In future I will run stabil in every tank that will sit for two months or more to avoid ethenal gumming of the carborator. I will start and run the generator every thirty days. I will get the RV out on the road every thirty days to shake the mouse out of the house. I will put mouse bait and traps outside the coach as well as inside. I will use peppermint oil as a spray above the gas tank and other places as my Tennessee advisors tell me that Tennessee mice do not like peppermint.
I will hope for the best.
That is about it. Let me know if questions. I guess won’t be buying that new set of golf clubs for awhile longer.
Happy travels and best Regards, 2travel
