Getting ready to rebuild the Zama C1U-K11 carb on my Echo blower. Getting a Zama OEM kit from RepairClinic. Just wondering if it was worth the extra $$ since there are so many aftermarket kits out there? I bet they all come off the same line in China. Justified or not, I always feel better with OEM stuff. After all, this carb has performed great for over 30 years. Thanks.
