Where can I get a main jet assembly for my D15 SII? It screws into the front of the carb...I took it off to see if it was ok (tractor goes into a sputtering fit intermittently and I have to choke it to get it to smooth out)....the jet body appears to have been brazed and the needle doesn't fit properly. I hope this is the problem....

My D-15 series II does the exact same!!! I put in a new carb. kit and it still acts like yours. I hope you can find an answer. Marlyn

Marlyn my 170 gasser used to act the same way....after fighting it for 3 years I found out the main jet seat was loose and floating around inside the carb...this jet is setup different, but I am hoping it is the cure.
