        I'm sure everybody knows the procedure you're referring to, but just 
in case, I should point out that Eric won't get very far spraying 
NON-volatile liquid around the carbs.  Eric, use something volatile 
as heck, such as ether starting fluid.  If you have a vacuum leak in 
your induction system, it will pull the ether into the intake stream 
and cause the idle to go up.

Graham, I know that was certainly a typo, but I could just 
picture Eric happily spraying water on/around his carbs, wondering 
why nothing was happening. ;)
