Carb tunning/mod question

Too lean does't want to idle in gear, gives hesitation, and takes forever to warm
up. But too rich sucks, too. I've used aftermarket metering blocks w/replaceable
restrictions. Only complaint- power valve channel restrictions too small to drill to
what I wanted. But if you had one, you could dial in idle system(idle feed restrictioj
size-probably .002-.004 over current size) and do that to your original metering
block.
