Carburetor Rebuild Overhaul Kit For Zama RB-145. Complete Kit That is OK for 10%+ Ethanol In Fuel, Includes gaskets, diaphragm, welch plug, needle, and inlet lever.

I ordered this kit for my Zama C1M-EL37B chainsaw carb. Everything was correct except for the one diaphragm. What's pictured in black is what I needed (with the screw hole in the center) but what came had no center hole. Instead it had two screw holes on opposite corners. The other holes weren't right either. I rebuild the carb with what pieces worked, but in the end, it didn't fix my issue.
