European adventures in a 200 turbo

[Richard van der Hoff]

Well, it was certainly a great suggestion, and we found a big split in the michelin man hose. A load of self-amalgamating tape later, a mixture correction, and we thought we'd be sorted. We also swapped out an HT lead which had very high resistance. The other leads didn't seem great, but weren't too bad. 

But no improvement :(. We've also lost the kickdown on the auto box, which makes matters even worse, though it's probably independent. 

It's certainly running rich, based on the soot coming out of the exhaust this morning. So really we're back to hunting for air leaks and weak spark. To help narrow it down, is it fair to say that an air leak would lead to sooty plugs, whereas weak spark wouldn't (as the fuel is just going out of the exhaust)?
