If you recall, my RV has been sitting for around 6 years with a bad engine. I bought it for basically nothing. The owner said everything works, and so far he has been 100% correct. He also said he put Stabil in the 80 gallons of fuel when the engine failed. But, the generator would not run unless I put the fuel supply into a 5-gallon container of fresh gas. Today, I decided to siphon 5 gallons of the "bad" gas out of the RV. I dipped the generator feed into the "bad" gas. Holy cow it runs. If the generator will run, then so will the new engine!!! I was dreading sucking out and disposing of 80 gallons of bad gas.
And...the weather is finally cooperating. I'm going to do the underneath work today in order to prepare for the removal of the old engine.
