Is it a "Clunk" or a "Click"? If it's a click, rap the starter solenoid with a hammer... Fortunately starters are both cheap $80 looking around and easy to replace (2 bolts, a nut and some whires) - or take it out and bring it to a place that reconditions them - not sure where on the cape.
If you can build a surfster you can swap a starter
