Sounds like a "OK" buy to me, you'd know your market best though. The hard start is probably dirty carb jets and circuits. Never a bad idea to check compression before buying. I always just factor in a new bore and piston set, then you know what you have.
I always look over a new purchase for rounded off or missing or mis-matched bolts, indicates poor repairs and that stuff bothers me to know end.
That actually looks like a pretty nice one in the pic, but the frame color indicates it's been completely apart.
Oh, and hey, Welcome to BansheeHQ!!
