Gary,
 
    You might loose the hair on your knuckles and get a  scare but the 
flash of fire from a backfire shouldn't hurt you. Lifting the  piston will lean 
that carb. Makes me think you might be trying to flood.

Nathaniel,

Do I understand that the pistons in your SUs have  a history of jamming?  
If 
so, fix that problem.  You should not  have to lift the pistons while 
starting -- lifting the pistons only  dilutes the mixture going into the 
manifold.

The carbs need to be  mechanically correct, pistons, needles, nozzles and 
float level before you  can reasonably expect the car to start.
