Hi To All,, I Have A Devilbiss Sprite And When I Try To Spray With It I Just Get Like My Paint Blowing Back Through The Pot, Has Anybody Had This, If So What Am I Doing Wrong, The Airflow Works Great, When I Pull Back The Trigger To Release The Paint Without The Air It Drips Out The End Of The Gun, But As Soon As I Try It With The Air It Just Seems To Bubble And Blow Back,, Thanks For Your Help...
