Once again, I have brought Willy for our home in Texas (800’) to our cabin in the mountains of NM (6500’). He has been home for couple years and been running fine, even on warm days. I bring him up here, and like last time, he seems to run fine for a short period of time, then out of the blue in the middle of the road, it just looses power and dies. Won’t start up, then couple minutes later it will start and run for 10 yards and same thing (at least I got out of the road). I can see fuel in the fuel filter plastic bulb. Wait 5 minutes and it will start and run but seems like just on the verge of lack of power. I know what I think it is and a possible solution but I want to hear input from y’all.
