I have (2) Super E-Z's, one's my runner and one's my parts saw. My runner needs some carb work. I pulled the carbs off both saws and found my runner had a Walbro HDC-44 and my parts saw had a Walbro HDC-64. What is the difference between the HDC-44 & 64 and which one is correct for my SE-Z?

Both carbs can be used on your SEZ.There was an earlier version - the HDC4 that came on the early EZ saws.There's virtually no difference in the carbs other than the circuit plate had an attached metering lever on the HDC44 & HDC64 whereas the HDC4 had a removable lever which was quite a pain to try to get that onto the metering spring.
