2003 HD dyna superglide, bike will not idle and

What do you mean/ How did you test no spark and weak spark? Does the bike run at all now. What history of the bike leads up to the present problems. Confirm that it is a 2003 DYNA. There is still a front and a rear plug wire even though wasted spark ignition but exhaust stroke spark is weaker than power stroke spark so do not have plug wires mixed up. Spark has nothing to do with air/fuel ratio so you have more than one problem from your information. What is cvp? what jets size do you have in the carb? Do you have only a stage one breather or a full stage one including exhaust??

How long does the enrichener have to stay on? How does it idle and how id its running performance with and without the enrichener on and how far on do you leave it etc?

Please post a comment with additional information and ALSO if you find the answer so others will share in your new knowledge etc.

Your problem is far more serious than something a little Sea Foam will fix. I would guess that your slow speed jet is clogged up or you have a major vacuum leak somewhere. Look for the vacuum hose that plugs onto the backside of the carb and see if it's come loose. But, if your bike is equipped with the vacuum operated petcock and it's evidently working, this is probably not the problem. You could have vacuum leaks at the intake to head junction as well. If the bike was allowed to sit up for an extended period of time, the gasoline left in the float bowl evaporated and left behind the "varnish" that has plugged up the jets. The carb needs to be completely disassembled and all the small passageways cleaned out by soaking it in a commercial carburetor cleaner.

Good Luck

Your carb probably need going through. I would suspect that it's your accelerator pump has got a few holes in the diaphragm and maybe your slow jet is partially stopped up. If the bike has been sitting for an extended period of time, this is more likely the problem. The air mixture is not adjustable unless you or someone else has removed the "anti-tamper plug" that covers the idle mixture adjustment screw. And, only then if you or someone else has turned the screw. If the fuel air mixture has changed, it's something wrong inside the carb. I'd either take it apart and clean it or get someone else with the proper experience to do it for me.

Good Luck

if all else on bike works, not a fuse problem, it would share with other components. remove and check for loose wires. if mechanical attached to front wheel, remove cable form front wheel worm gear and check if square cable is broken (pull it out)

2003 is single fire. If you buy anew tach, it will come with instalation instructions. With a little common sence, it's pretty easy.

Hi !
Guess your bike idles well but when you acclerate the engine dies down to a stop...

This is for 2 reasons....
1 dirt in the carbarator
2. The spark plug has shorted .. get new plugs..
All will be well

yes it could cause this
fully charge battery and try again
