F2 Carb Sync

F2 Carb Sync
Ok so my bike has a MAJOR hesitation between about 3-6k RPM...it is soooo sluggish.
So I bought my joint boosts, built a homemade manometer, and hooked it up.
However, carb 3 pulled the 2-stroke oil SUPER fast...way faster than the rest.
What is a better way to do a carb sync? Nobody in my area seems to do one for these bikes anymore.
Which way do i turn the adjustment screw? I cant even leave the bike on long enough to do an adjustment...the oil would get sucked in the carb and white smoke my garage
Thanks,
Brandon

Before I did my carb sync, I inspected the throttle openings while the carbs were out for cleaning. With a flashlight shining on one end and looking through the other, I adjusted the sync screws until all openings are as uniform as I can get them. When I did my sync, I barely had to do any adjustment. I learned to do this with my older Virago V-Twin.
In your case, I'd expect the opening on carb #3 to be bigger than the others. If not, there maybe other issues - not uniform compression, vacuum leaks, etc..
As suggested above, you don't need to take out the carburetors with a sync tool.
