Can a "shade tree" mechanic like myself do this without a major cluster F*#k? I know how to label, sort and be meticulous, and how to do one at a time. On a scale of 1-10 (1 being an oil change and 10 being clutch replacement in an XKE!) whattaya think?
Ken P.S. Bought the car after it had sat for years. Rode it home from CT to MD and it ran fine for about 150 miles. Then it began to act fuel starved under any load...up hills, accelerating, etc. It gets worse day by day. I've changed fuel filter (pretty clean actually), plugs and wireset. Should I clean idle jets first...before attempting this? Any chnace I'll get the thing running again if I do this? |

You can do it. The book will tell you how to set your mixture screws for easy start-up and tune. I like 2 1/2 to 3 turns out and then turn in to best tune. Get the size of your idle jet and main jet, ET and venturi when you take it apart and post it here. We can see if they're sized correctly.
What you might have going on is water in the float bowl. Water in the air condenses in there and sinks. It then corrodes the aluminum in the bowl. You'll have to scrape that gunk out of there. The same will happen in the accel pump. Clean all that stuff out and soak it. Your floats should be fine. I've never seen a sunk IDF float. I think they are real light solid plastic that floats. I've never cracked one open to check if it's hollow so don't quote me on that. |
