Flattie bought himself a Scorpio, came complete with a nice carbon black plug and wouldn't idle much at all. Replaced plug, idles fine now when cold.. but when hot likes to run up to ~4k rpm till you give it a good punch of throttle then calms down for a bit. Next idle time revs right back up.

Not quite sure where to start, don't even know how to pop the tank off and have a look at the carb. Thoughts or a workshop manual would help. Cheers !
