Hi all
I have a problem with my os. 40 fp going lean very quickly, especially in a nose up attitude. I have had this checked by MANY experts and they have all come to the conclusion that it is not the tank and lines, so please don't go down that route, the problem is that the engine isn't great. My question is, would a one way pressure valve or check valve between the tank and muffler help supply a constant pressure of fuel to the engine? Thanks
