    Simple carb question please

    I have a set of 78 bs38 carbs. These are not mine but same carb for reference. What is the small tube located on the bottom right of the carb please?the reason I ask is I had my carb apart recently and I noticed a small crack on the outer sleeve of this tube.

    Ok thanks very much I will make sure to set the float levels I did not adjust them when taking the carbs apart. I definitely appreciate the advice. I can keep the bike going if I make sure to stay on the throttle so hopefully this is it.

    Yeah to my research I was also surprised to see no serial number there and then I found that some bikes has a number located behind the oil delivery tube and so that’s why I included that pic also. I will look at the valve cover in the morning.

    I used the rebuild kit from mikes-xs the sizes were all the same but the pilot jet did have a different hole pattern and I decided to go with the new one. I left the needle setting as the bike to my knowledge was stock and I made sure to count the turns on the air screw at about 2 1/2. I...

    Ok so after giving it some riding I’ve realized it is only when I brake hard very distinctly. I have turned the idle up to maybe 1400 to compensate a bit and with a blip I can keep it going every time it’s just a fickle process.. I’ve noticed a small leak in either manifold or possibly a...

    So in recap it doesn’t always die when I stop, just sometimes and not right away every time it’s very inconsistent. I am making a list of things I can try to diagnose and I will update for anyone interested or who stumbles across this thread in the future. It has helped me many times. Also I...

    If you know of any ways I could maybe confirm or not it is a fuel issues like maybe I could bring a wrench and empty the fuel bowl or something when this happens I’m not sure. Thanks again in advance to anyone with advice.

    No I don’t believe it’s electrical because it does do it sometime without leading to the “no start” condition. Sometimes it’ll just make a hesitant noise then stall and I can start it right back up almost as if when it’s really bad when it won’t start very much strikes me as flooded in that...

    Some background on the bike, it’s all stock and I recently rebuilt the carbs and synced using a digisync. Bike seems to make a “puffing” noise and die while pulling to a stop sign at near full stop. Bike will be impossible to start for awhile until I let it sit for after that. I did not set the...
