Well guys, we have an operational motor! After a 72 hour pinesol soak, quick dip in a neutralizer, thorough rinse, brushing scrubbing and dry with compressed air (and new, hotter spark plugs earlier in the week) the motor now sounds like a completely different engine.
Thanks a ton to all who helped. The simple things did the trick.
If anyone has a minute to check out one more motor, my brother in law just picked up a 1981 Evinrude 15hp. Runs well, dies down at idle, not as bad as mine did tho. We believe a thorough carb clean will do the trick, but in case there is anything we aren’t picking up on, we figured this would be the forum that would point us in the right direction. Just in case there’s any other suggestions/tips/tricks.
