Now if I had to buy the complete overhaul kit I'm not too sure I would have fixed the nailer. Reason being, the big box stores are always having a sale and a new one could be found for 30-50 dollars more with a one year warranty. Unless, I already had an abundance of nails that were specific to the old nailer then I would fix the old one.
Good Luck with your project and may the force be with you!
