I have pulled the carb apart twice ...and it will only run with choke on..yesterday the bike flooded itself and filled the jug..exhaust and carb with FUELl...

Maybe a busted reed ?

NEED HELP PLEASE

OK, you cleaned the carb but did you remove the pilot jet and clean it? Did you remove the brass needle seat and clean? Did you remove the choke unit and clean?
Doubtful on the broke reed.
The screw on the side is the idle adjustment.
FYI:: Petcock:: In the on position, fuel will run out only when the motor creates vaccum (the line furthest to the back of the carb). In the prime position fuel will run all the time.
We'll go from there. [img]i/expressions/face-icon-small-smile.gif[/img]

 

THANKS FOR YOUR HELP I will try that and let you know


GREATLY APPRECIATE YOUR HELP

 

In the prime position fuel will not run all the time, it will run until the bowl is full then the needle and seat should close once the float rise's. So if you filled the jug, its because your needle isn't fuilly seating.

Check for vacuum leaks between the carb and intake.

 

Well actually, filling the cases is caused by the hydraulic weight of the fuel pushing by what little pressure the float gives. This is why bikes have to have the fuel shut off.[img]i/expressions/face-icon-small-wink.gif[/img]
I explained the petcock operation so he could understand the correct workings of it.

 

had same problem not more than 5 days ago. remove carb. and clean. take jets out of carb. it will work after that. also, no cheap oil!!

 

THANKS FOR YOUR HELP......I cleaned the pilot jet and it runs like new...Pilot was plugged shut ..so i cleaned it with carb cleaner and then blowed it out with an air hose [img]i/expressions/face-icon-small-smile.gif[/img]

 

Glad you got it. Better off then me, I gotta replace my entire jug.

 

SSS~I was reading your Duinli post. Not sure if you were asking or explaining. [img]i/expressions/face-icon-small-smile.gif[/img]
Why do you need a new jug? No overbore?

 

Give's me a reason open it up a little........

I could bore it, probably get away with honeing and putting in a new ring and pistons but, Why not just throw on a 52 mm jug thats ported etc................[img]i/expressions/face-icon-small-happy.gif[/img]
