Ferrari Mailing List: Re: 328 run on

[LarryT (l02turner]

Howdy,
   First, make sure all the vacuum lines are in place properly and not 
damaged.  A vacuum leak causes all kinds of running problems.  If these 
hoses have been in place for nearly 20 years they may have dried out and 
become brittle.  Also check the ignition settings to be sure they are 
correct.  If the timing is slightly retarded it can cause run-on.

   Also, you wrote that you <<<tried messing with the fuel/air mixture 
>   -- that's not a good idea.  In extreme cases damage to the pistons can 
result.  There's a procedure to flow when adjusting the fuel/air mixture 
which normally requires a gauge of some sort.

   Good luck -
