6600 John Deere Tune-up info needed
Hello, my brother-in-law just purchased a 6600 JD combine, with the 303 gas engine. He says it's running a little hot, but other wise runs pretty good, but maybe a little underpowered.
He want's me to help him give it a tune-up.
Does anyone have the tune-up specs for the 303 gas engine?
It's serial number 25099.
Timming, point setting, spark plug type and gap needed.
