[AJD] JD 70 running rough

[John]

Troy, I might be able to lend electrical/ignition advice but NOT carburetion 
on that tractor. First thing I would do is check the ignition points (under 
distributor cap) and clean/polish/buff and gap them if they arent in too bad 
shape buttttttt replace them and the condensor if they are badly burned or 
pitted or all carboned up. Make sure the distributor cap is clean n water n 
oil n residue n dust free with NO CRACKS and the rotor tip is okay and the 
lil carbon button at top of the distributor cap. She may just need a general 
ignition tune up and a carb adjustment,. make sure the air cleaner bowl is 
water free also and insure she has fresh clean water free gas .
