Hi sh2006,
Welcome aboard the Scott Bonnar train. You're certainly correct in saying the bug has bitten because it bites hard and injects a passion that's hard to revert.
You've got one of the most unique Scotty's there that was made back in around 1975 when they painted the chain cases and handle bar shields in that challenging black and also came out with a decal that to this day hasn't been reproduced as far as I know and that's the one with the red outline which was run for about a year before it was scrapped and replaced with the black and white unit.
Now considering the age of it I would check out the clutch thoroughly and see if there's any left to right movement as it's slowly rotated with the pull starter.
Let me know how that goes and we'll move on from there.
Cheers,
.
