I have my bike running, but it runs rough. I've adjusted the timing and fuel/air screws on the bottom of each bowl to the appropriate spots. I noticed gas leaking from the rubber tube between carbs 2 and 3. It looks to have a split in it from age. Will that make that much of a difference in how the bike operates? (PS. I removed the carbs this afternoon and am replacing the black tube anyhow, but I was just wondering. My goal was to hear the bike run. Now, I've set the bar higher and want it to run right!
