Wow, has the drive train really got that much of a kink in it? 

Here's the pic from the Register write-up

And another off Google Images

I realise none of these pics is absolutely dead straight on, like yours is, for a good comparison.

Weird, eh?

You're right. The Register photo above, and the video from underneath both look like it's swung over a little. I guess there can't be too many ways to get the engine mounts to fit the chassis. As long as the carb is clear of the engine cover, then I guess all should be well!

Have a look at this, too. Some good close up footage of a (presumably factory built) 160. Nice shot around 1'40"
