Hi all, my Sprint 955 RS was sitting for five years in a heated garage. Jumped the battery and it ran, blew nuts and seeds out of the exhaust when it fired up. Lots of mouse mattresses under seat. With the fuel being so old I thought I’d pull the tank and also clean the rest of the mouse mess in there. Put the tank back on (didn’t fit anymore, no surprise it got long) now it will only fire when on the start button. Like it’s trying to run but can’t get enough fuel. It’s getting enough to fire a bit but as soon as I let off starter button it’s done. I obviously did something stupid when I had the tank off. I only disconnected the fuel line quick disconnects, the vents, pressure reg hose, fuel pump connection and reserve light connection. The fuel pump runs when key is on, however it doesn’t seem as loud as it used to be but I’m not certain of that. Pulled fuel line with key on and has steady flow of fuel. Why didn’t I just run that old fuel through it?? Anyone have any ideas? Thanks in advance for your help.
