1. i repacked a nova 390, but the motor it still running lightly. i repacked accordingly but i think it might be an electrical issue.
2. Video is very well done. None of the others on YouTube are as detailed. The wiper in the kit I had was thicker than the old one requiring the removal of a washer that was under the shoulder of the bottom valve of the piston to get the right length of packings . I differ from tightening this all the way before inserting in the cylinder. It expands the packing too much. Tighten after its assembled. Do not over soak the packing so in oil. They will expand too much making for a harder assembly. Soak them only 5-10 minutes. I used 20 weight oil. Weight of oil probably does not matter.
3. Brian! YOU ROCK!!! My partner has a painting biz and I was given the "opportunity" to repack his sprayers ..... I have never even operated a sprayer let alone taken one apart. I could not have done it without this video! You explain things far and above any of the other videos I watched and got me through a successful rebuild. Since then I have also done a Graco 695 THANK YOU SO MUCH, you have saved us tons of money and time .....
