I got a Onan NHC off marketplace today for $160. I think price was decent considering onan parts. Supposedly runs and has 600 something hours. I tend to believe more hours than that by all the caked on grease. The carb apparently has a issue he thought. I really didn't need it but I heard NHC are not plentiful to be had..Not that cheap anyway. Has decent compression by what I can tell just turning it over. Did I do ok..Or waste $160? I do need a starter on my running mighty mac with onan..but if ever change that I will buy new or rebuilt one since such a pain to get out. Mine misses about every 3rd attempt to crank it over.
