Update: I tried silicon spray along with working it into the boot carb joint by wiggling, the the pull back and up motion. No luck at all.
Next I tried a large kettle of boiling water (maybe a gallon max) and drissle that over the boots (probably took 2 minutes to pour on all relatively equally) and that got it off using the same pull back and up motion as before. I probably only applied half to 3/4 the force as before. The carbs looked spotless downstreem of the butterfly (i know thats not the whole story - wish it was). I dissasemble the carbs from the rack. Findings: The center and two outside fuel joint sets had orings that had split circumferentially and 1 of the 2 air joint sets had 1 slit oring. Needless to say i'm need to order them (at least get Parker O'rings as i like to know exactly what i'm buying if it's not OEM parts). Well - i guess i should venture into the carb to see what it looks like, my only hesitation is i'd like to try and get it to run with a little tampering on my part as possible (to aviod the is it something i did to it questions if it doesn't run so well). Any thoughts on how to minimally investigate the interior of the carbs. I do have the Honda shop manual - just lacking experience.
