52Carl, these things have a way of happening. Jerry always has good advice and his willingness to help is commendable. I have had unbelievable trouble with a Model B. The ones I rebuild for others have all worked but not mine. Three times apart and some type of problem (s). I could not believe yesterday, all buckled up and gas coming out of pump rod. Managed to take off just the top, float level perfect and then......I took out floats. microscopic hole in soldered seam. This simple but overlooked problem has cost me hours of frustration not to mention money spent on gaskets. But with it goes the satisfaction of FINALLY getting it right. I can vision Jerry shaking his head. Ed
