[DeTomaso] Webers - update

[Julian Kift]

If you have a center pull throttle linkage, you can play around with the bellcrank ratios to make it more progressive, at least that is what I have done.

> I still have an issue with the linkage. I spent most of the day on Sunday getting the Webers sync'ed. I hooked up the last bell-crank at about 4pm. Rather than fooling with the linkage, I drove it - carefully. It isn't binding or anything. It's safe. It just opens too fast. I'll finish the linkage over x-mas.

> 2. The driver's tailpipe is smoking a little bit.
> 3. The exhaust sounds funny. It's hard to describe. It sounds almost like a piston slapping, but you can only hear it in the exhaust, and only at certain rpm's. I haven't spent a ton of time listening. There's only so much my wife will take - or breathe. She was working on her wood-working project in the driveway, right behind my car.

> I haven't checked anything else. Any ideas of what to check next?

> I plan on having the car painted in January. When I do, the engine will come out. At that time, I'll take it apart to make sure all is well.
