I have 2 FD-11's and like em. One of mine is electric start. Is yours? As usual, check compression, that's the biggie, the rest can be fixed easily... if it's all original, you'll have to redo the ignition and carb...
That's a reasonable price. I'd try for $150, but $200 isn't out of line. Of course, everything depends on price and I'm assuming its a nice original, which may need the usual attention. Full tune-up and gearcase reseal is in the neighbourhood of $200. So check it out closely since $200 + $200 = more than its worth. We really must be crazy to pursue this hobby!
