no idle running rich

pretty

New Member
Have a 1986 1100 Sportster w/ SU carb. NO previous problems
No idle
Running rich, backfire.
Tank was dirty, just quit
Tank cleaned, fuel lines, and carb.
Ignition changed
Plugs slightly wet.

Thoughts?

Check your float level and needle and seat, maybe trash in there:s
 
Was the carb rebuilt or just cleaned? Can you, and sorry for not knowing, pull any codes on the scoot?

I dont remember older bikes like this been able to throw codes and you would probably need The Scanalizer to read them, JMO
 
The only scanaliser that will work on a bike of that age is a good mechanic with a good bit of experience
I would start on the carb not that i have ever touched that type of carb so cant help on the specifics
it may just be that a jet has fallen out
