[DeTomaso] Troubleshooting Carb

[astephens]

Thanks Will,
     I think you are right about the adjustment.  Instructions in the 
Pantera Technical Information folder lead me to believe turning the screws 
in would lean the mixture.  I also think it may now be a timing issue. 
Apparently there is a ignition retard feature that retards timing ten 
degrees during prolonged idling if the engine gets too hot.  I suspect that 
valve is retarding my timing more often than necessary.  I will try 
bypassing that thing and see what happens.  I also discovered that I need a 
new coil wire as it is making an interesting light show after dark! One more 
issue is that I think the float level needs to be adjusted.  I'm pretty sure 
that there is too much fuel in the bowl leading to a leaking carb.  I'm 
looking forward to what will hopefully be a productive day of Pantera 
repairs.
