Question about Motorcycles
I have a 1983 FLHS Shovelhead, and it ran good 2 yrs ago before I bought my new ride. It will not idle even with the choke full on. Can't figure it out. I did the following: I had to re-paint it (applying for collector plates), replaced the starter motor, solenoid, spark plugs, took Carb apart and cleaned it. It will start, it will stay running as long as I have the throttle on but as soon as I let the throttle off, the bike dies. I can see the gas squirt in when I turn the throttle, not sure what to do next. When idling, does the fuel enter the carb by a pump? or by vacuum system? I could change out the fuel lines but not sure if that is the problem. Any other ideas?
It seems the idling jet (primary jet) is clogged, try to blow it out and see.

Carbs gummed up. Need a serious cleaning or a full ruubers replacement/rebuild kit. Gas turns to gummy when left stting in the fuel bowls.
Use a couple of cans of Sea Foam.. best stuff in the world.

have you changed the fuel filter? you are not getting enough gas, are jets squeaky clean? there is a good fuel system cleaner in the USA called Berrymans B12. put some in the tank warm up bike then let it stand overnight and see what happens. if still no luck repeat process. if you still have same problem then get new fuel filter

Get some carb cleaner. Remove and clean the Nozzle, choke and main jet. Remove the pilot jet and air jet but count the number of turns to remove each one and put them back the same number of turns. Don't mess with the needle or clip or the pilot screw and plug at this time. Clean the carb thoroughly. Don't get carb cleaner on the diaphragm. If able, submerge the carb in cleaner overnight.
Let me know what happens by posting a comment.
