Hi Paul!!

I have a DA50 and what a nice and impressive engine!!

My needle settings were out by quite a bit when I got the engine so I started at 1 1/2 turns out on each needle and slowly closed the low 1/16 of a turn till it ran good, but don't forget that when you play with the low end it also affects the top end so you when you close the low you will have to open the top at some point
