Hitachi air nailed air leak fix.

Air was blowing by the trigger. I put some rubber washers in to fix it but it didn’t work so I found the proper washer online and was able to seal the air so now it fires great. I recommend but it is not required to take apart the top if the cylinder head and clean it out and oil it up. I found a tiny stone in my cylinder head seal. Removing it prevents damage beyond repair. Comment if you have any questions.
