RLS,
Thanks for your reply and for helping out a fellow Newbie.
You hit the nail write on the head; the new rig came with a complete set of (0°, 15°, 25°, & 45°) nozzles. But I decided to save these tips except for the green nozzle and combined it with an older set I had. But due to my ignorant and lack of knowledge (Newbie) I mixed tips of different sizes. Consequently the only one worked was the green nozzle, which again came with the new rig.
Thanks again
SAMNSON
