Hello, I just finished a top end rebuild (with some help from this forum) got everything back together, went to hook the carb lines up, and notice I seem to be missing some external pieces? There seems to be no end for the main fuel line to connect onto, just a hole leading into the carb. I was able to drop some fuel in through the opening and it does start. Just wondering where I should get this part and what else if anything seems to be missing? Pictures attached. Thank you!
