I used this video to rebuild my carb 7004468 which I researched to be a R1-B from my 235. The video was awesome because I was able to follow it step by step. The close-up video I took also came in handy. At 25:50 Mike, the gentleman that made the video is talking about how there could be two holes in the accelerator pump well. I technically have two holes on the side of the well but one of them appears to have a stuck aluminum check ball that can only see from outside of the carb. It didn't seem to be the one "on the bottom" that he was referring to since it is technically not on the bottom but directly across from the other one on the side wall. I wasn't sure if we were both working on the same exact carb. I left if jammed in there to keep gas from leaking out of the carb. Can anyone confirm if this is correct? If not, what is the hole leading to the outside for and how is gas kept from just leaking out if it wasn't plugged? Thanks
