[alfa] Winter Projects!

If it splashes high enough.. the distributor is right..  possibly also 
the spark plug wires are leaky and a big dose of humidity (steam from 
exhaust pipes) could be shorting you out.  How long does it take to 
recover (it does recover,  right?)

Those are smaller in diameter..  there are a few sizes that are near 
correct for the right size rolling diameter (causes car gearing to be 
the same, and speedo not to be wrong) and that's not one of them.. 
Look for a tire calculator that can tell you what sizes are right for 
the original size (equiv being 165/78 or /80 -14)  I don't have the 
URL,  but there's a Miata site that has one,  some tire sites as well.  
Off the top of my head,  and probably wrong,  I think the correct ones are:
185/70 -14
195/65 -14  I think this is the closest to perfect size wise.
205/60 -14  Some say this is too much for a street car,  really hard 
cranking in parking lots.

If you keep in a close to stock diameter,  the car will be no taller or 
shorter than it was,  as well as the gearing being the same and the 
speedo reading right.

Lots of Digest discussion on tire sizes, ride, reccomendation to dig up 
searching the archives,  too..

#4 I thought I answered in another message,  but haven't seen it show up 
yet..  Check the center flange of the driveshaft for tightness.. very 
dangerous if it's coming loose.  Also look at your rubber support for 
the center bearing and the bearing itself..
