So i'm finally getting a handle on tuning my phbg and i never would have thought there would be such a difference between .5mm. I've studied the spreadsheet for the garelli's inside and out, the only 2 19.5mm's on there are running main jets in the 100 and the 19 is down in the 90's. I thought to myself, this can't be right but low and behold i got my garelli up and running today running a 93 main. Started plug chopping and i was getting lean results all the way up to a 99 (the largest i have), it's still lean but looking better. My lowend is coming around with each upjet and hopefully tomorrow it should be dialed in.
Anyway just wanted to say thanks for all of the help and once it's sorted out i'll post the results along with some finished pics of my little winter project.
