If you use anything to hold the oring in place. I recommend Vasoline. It de-solves in gas and heat.
The #60 pilot is the main thing for the hesitation cure. Pilot screws are right at 2 turns out. When you go back together, make sure your accelerator pump works.
Check sync on carbs. I recommend replacing fuel filter AND fuel when cleaning/rebuilding carbs.

I have removed stock NEVER touched before carbs on bikes. From the manufacturer they have some type of sealer on them. It acts like silicone.(Honda and Suzuki) NOT all but some.
If you do many older carbs, some of those orings just don't want to stay in the groove. You have to buy a whole gasket kit just to replace them. Kinda pricey for just one oring.
I try not to use anything...but there is always some that just wants to be stubborn.
