Thanks for the pics. Yes, the one I just bought looks identical to one you tried, the one with the silver top. It’s like you have depress the arm almost an inch before it does anything! I guess I will attempt to source an original one and either it or of I can find one already gone through. I called the “filling station” parts place as someone suggested,
but he said they are out of stock on OG pumps and not sure when they will have more. They do have the rebuild kit though. Ill try ebay maybe, or post on here if someone has one for sale.
So, what do you think the odds are that this is the issue the whole time? do you think it is possible that the pump I had before (which would work most of the time at low speed), but then what caused the symptoms that I’m having once I get up to a certain speed???
