did you burn an exhaust valve? if so, when was the valve job done. seems to be common on these motors
Yes it was a exhaust valve on the #1 cylinder. From what I know it never had a valve job. It was skipping a little when I first got it running but eventually got worse after I ran it a few times (less than 10 miles). I just want to make sure its not something i've got wrong that made it burn the valve.
