Hi !
Just joined after purchasing SB33 from the bloke across the road & not knowing a thing about them.

So like a kid at Christmas, I couldn't wait to get it home and start to tinker.
Check all over for anything that may look to be a bit suspect.
Didn't find any that rang alarm bells (easy to say when I know nothing about them) so put some fuel in and pulled the cord.........
Sweet as! The 3.5 BS kicked and didn't miss a beat.

So it runs well, but the clutch will not disengage (I worked this after reading some of the posts from the members of this forum. Thanks) it look like the bush that puts pressure on the housing is very worn.

Before I get suck into full restoration, how freely available are parts for a SB33?

I'll post some pictures
Cheers
