Re: alfa-digest V8 #839 (mercury substitute)

[DickBevins@domain.elided]

Mercury is 13.6 times heavier than water and has no surface tension to the 
glass tube in which it is contained. That is why it is used in a manometer or 
carb balancer. No other material that I know of has anything close to the 
above properties. With EU environmental regulations being as stringent as 
they are, you will have a tough time finding legal mercury. (I suppose you 
could vandalize a bunch of home heating thermostats for the switches.)
On the other hand, I used to have pretty good luck balancing carbs with a 
pingpong ball manometer designed for motorcycles.
