To All,

Before putting in all sorts of stuff, Turn THE FUEL FILTER around! It only works if it is installed correctly. This is a personal experience: We were traveling out west going to Tucson and stopped at Carlsbad Caverns for several days. While there one of our traveling companions opted to do some small maintenance on his engine. When we left to continue our trip the coach would run great for a short time and then it would run out of power. We fought that for better part of a morning at the rest area just south of Artesia, NM. Looked at everything, change the fuel pump and several other things and didn’t look at the fuel filter as he said that it was new and he had changed the day before. After more screwing around, one guy said, “Lets Check the FUEL FILTER”! Found that he had installed it backwards and it was restricting the fuel flow to the carb. You have to understand that this group of 4 were very knowledgable and we all missed it at first. Damn, ran well for the next 4 months and home to Ohio for him and for several years after that.

I have got group of pictures that shows how to correctly put the fuel filter in the carburetor.
