Sportster carb - XL 883C Sportster Custom Harley Davidson Motorcycles

Either the needle and seat are not fully seating and sealing OR the float level is not set right. Where is the carb leaking from, internally or out the overflow?? That is the nest question.

There is probably a small leak in the intake tube to that cylinder. Remove and carefully inspect and reinstall carb and induction manifold.

Maybe u need to get a new carb... try this once

Is it backfiring through carb or exhaust? Has it been sitting for any period of time? We suspect carb issues. Try cleaning carb, pay special attention to the pilot jet and main jet circuits. Clean with spray carb cleaner and air, do not use wire. Make sure needle and seat are clean.

If your bike sat for that long with fuel in the carb, it's probably gummed up the carb on the inside. The carb needs to be disassembled and cleaned out on the inside. This is job best left to someone who is experienced in this area.

sound's like the carb is set to ritch, ther should be an adjustment on or just under the carb it's self

Remove the carb soak in carb cleaner, **** out small bleed holes with a wire from a wire brush etc. One of the passageways is still clogged, or the float is sticking.

To change the choke cable, you don't have to disassemble the carb but you may have to take it off the engine. The black plastic piece simply screws into the side of the carb. Once out, you'll have to take the plunger and spring off and put it on your new cable. Then screw the new cable into the hole. Reinstall the the carb on the bike. Always replace the carb seal on the intake where the carb plugs into it. Good Luck

You have a basic EVO designed engine with a CV carb.I dont think they have a TC Sportster yet.
