You say down line, where you pulling negative G (like pulling out of the line to inverted?) ?
The way the carb regulator diaphragm is oriented on the 50 makes it go leaner inverted. So you have to tune it with the idle quite a bit rich upright (the infamous DA burble), especially if you are using e stock WT201 carb as its high needle cant actually be tuned rich of peak. If you dont it will lean out when you flip inverted and will deadstick if you advance the throttle sharply inverted.
A lot of guys, me included, had improvement by switching to the WT76 (or the DLE carb which is a clone). You can richen up the high needle a bit which allows you to run the low end a little more lean with less ricsk of deadstick inverted.
