1947 2N Front Mount Distributer 12V –Ran low on poweer after disking for a couple hours last weekend.
Checked points as advised and found no problems. Fuel flow was fine from bottom of the carb. Found weak spark with adjustable spark checker. Charged battery and started up and ran good. Disked another 45 minutes before it started running rough just as before.
Found weak spark again. Pulled battery and alternator to have checked. Alternator checked fine. Battery checked bad.
Ran great again with new battery until it started running poorly again after another hour disking.
Fuel flowed freely again from bottom of carb. Charged new battery a couple hours. Tried again and it still ran poorly before parking it for the night.
Why would tractor repeatedly have weak spark after working it roughly an hour? Amp meter showed about 5 amps while it was working. What next?
Thank you,
