[Healeys] Why Don't depress the clutch ?

I agree with Peter and have heard the same about the throwout bearings.  I 
too was taught to depress the clutch before cranking, but this was before 
owning a British car. In fact, my old Supra required the clutch to be 
depressed before it would engage the starter.  It was my mechanic some years 
back that told me to always start these cars in neutral - clutch out. My 
first Healey was notorious for slow cranking and I found a dramatic 
difference when I stopped depressing the clutch - it would start much 
quicker with a stronger crank.  Even more of a problem was my E-Type, which 
at one time would hardly crank at all unless in neutral, clutch out. 
Mechanic also advised to go to neutral with clutch out when sitting for any 
period at traffic lights, etc.  He said the throwout bearings were too soft 
and would wear quickly otherwise.  I was at a Moss show up in NJ years back 
when a guy in a Healey next to me was having trouble due to a slow crank. I 
asked him if he had the clutch in and he responded "yes". I told him to let 
it out in neutral and try. It started right up. I could tell he was puzzled 
why.
