Throw it in the swamp .B = Big dumb carb...
I've only had minimal problems with my B on my ironhead Sporty in 25 years. Take the bowl off and make sure everything is good and clean. If it has varnished up a little bit, it will cause the needle to stick in the orifice rendering the bowl float inop. The easiest way to check and see if it's the float/needle, after it quits running, take the plug out of the bottom, and if no fuel, your question has been answered. If not, your mixture setting is probably all wrong and should be set back to factory specs for the carb.What you want to do is warm the engine up, idle 6-800 rpm and turn the idle mixture screw in leaning it until the engines starts to die. Don't turn it too hard in the seat as it will damage shit. Turn it back out richening it until it starts to die. A position about halfway between these points or a setting of about 1/4 to 1/2 a turn out from the lean side of the range is correct. From the fully closed position this is about 1 1/4 to 1 1/2 turns. That is straight from the S&S B carb sheet.I can't get my super b carb to run right.
It's cold today, maybe 40's out.
What ritual should I follow to get this thing to start consistently.
I just choked it and it started after a few tries, idled for a minute, then quit.
Now it won't start weather choked or not.
A guy I know says "pull it off and throw it in the Mississippi, it's junk".
I'm of the opinion that it worked 40 years ago it oughta work now. I want to figure this thing out.
Any advice would be greatly appreciated.
Thanks a billion in advance.
I'm pretty curious now! There is not much to these things. If it corroded up really bad though, the passages could be messed up. Hopefully that is not the case. Truth is, they are pretty reliable carbs. They obviously perform better in higher rpm ranges because of no accelerator pump, but on Shovels, they generally work better than on the lower c. i. Sportys.I've dismantled and dipped it within the last two weeks and everything looks good to me.
I'll try to pull the plug and see if by chance there is an issue with the float.
Thanks
...and thus easy to tune and use.B = Big dumb carb...
Yeah, no gas from the tank is usually an issue.Guess what. I was just reading this.

and I saw PETCOCK.
Realized I never turned it on today...........
Won't be able to try again until tomorrow, but I'm pretty damn shore that go cause an issue.![]()
What, turning on the gas before you start? Absolutely.I have a B on my "77 Sporty. Should I also follow this advice? Would an E with the accelerator pump be better for me? I like that they are shorter.
