Just a little update on the carb springs.  I did modify the Home Depot 
springs to duplicate the 300F-H units.  Upon closer examination, the spring rate 
seems a little higher than the stock spring---if that is what I have one of.  
However, full throttle opening is quite easily accomplished on the "F".  A word 
of caution, however.  I used the acetylene torch to assist in the modification, 
so don't know the ramifications of the changes in metallurgy.  A broken 
spring during driving could be a bit bothersome----to say the least!   I am not 
ready to drive the "F" yet, but will look forward to Jeff Carter getting in his 
properly heat treated repro springs.   Mine sure do look nice, though!     
300ly, Gil
