My JD4020 gas has a zenith series 69 carb, JD# AR45162, Zenith #13430. Found main jet solenoid bad. Replaced with manual main jet valve. Now starts but will not stay running and runs very rough. Need help. This is only tractor I have to move round bales and feed. I rebuilt this carb with no change, but did not adjust the float. Need the float level and float drop specs. Can anyone share?
Any other suggestions greatly appreciated. I did try brand new series 68 carbs, but tractor would not start at all without starter fluid then dies, so back to the original series 69.
