i rebuilt and cleaned my 2002 dyna carb. gas is coming in with throttle and vacuum piston move up with throttle and then bike dies immediately. to make sure carb was clean, i cleaned it a second time with the same results. any ideas? thanks!!

 

Does the bike idle? Takes 3 circuits to start/idle/WOT. No orifice shuts down or closes off meaning. Tank's gas cap vent is closed? Battery is 12.8v or higher?

 

Upside down needle jet is most often the culprit and very easy mistake to make.

 

bike idles just fine. brand new harley caps. brand new harley battery. thanks!

 

yes, needle jet in the right way. thanks!

 

Take that brand new Harley cap off.

What was it doing before you cleaned carburetor? If it's cutting out instantly, it's probably electrical.

 

What are Harley Caps? A hat?


Hey Babe...Like my cap?

 

tried it with caps off, same result. yes, it cuts off instantly. when i throttle the vacuum piston goes up a little. i manually lifted the vacuum piston and gave it throttle and it revved and didn't die. could that mean there is a leak in the vacuum piston? i checked it for hole with a light and didn't see anything. thanks for your help!! if it is electrical, what would i look for?

 

oh, it ran well before i cleaned the carb. i did rewire for new handlebars and put a new tank on it. cleaned carb cause i figured i might as well since bike was apart. all lights works. thanks!

 

Do you have the vacuum hose to the voes and petcock connected?
