Hi everyone,

Thank you for your responses.  I leaned out the carbs and that helped the 
start up problem and lessened the darkness of the exhaust somewhat but the 
exhaust still is whitish.  I put my finger in the tailpipe for a few seconds 
and pulled it out wet and sooty.  It seems to be running the same as when I 
bought it a year and a half ago only the exhaust seems to have a little more 
color to it.  And it seems to be getting worse slowly.

I had it checked for a head gasket leak about a month ago and the guy said 
that he couldn't find anything wrong with it.  However, he couldn't do a 
"sniffer" test because his setup wouldn't fit the car.

I think I'm going to pull the head soon just to see what is going on.
