Greetings....

My '70 S has Webers installed in place of MFI. They're out of tune and I don't of anyone here in Bend who knows how to adjust them properly. So I need to go ahead and learn how to do it myself. Does anyone know where I can find printed information on these carbs, including how to set them up.

I have compiled and published information on tuning Solex's, Webers and Zeniths for the Technical Section of the the 356 Registry website, but I don't know squat about the Webers used on 911's. Should be able to figure it out though with a little help.

One other thing....

The '70 also has headers in place of heat exchangers. It has what appears to be a stock muffler, but is definitely a lot louder than my '73 S that is equipped with MFI and heat exchangers. Is the difference in loudness due to the Webers vs. MFI, or the headers vs. heat exchangers. (My guess is that it's the Webers, as I find birds and other small animals stuck to the grille of my engine lid when I stop <g>).

Thanks,
John Audette
