the only changes, or mentionables from me:
use the turkey "flavor injector" syringe. works great and easy.
use coarse sandpaper or a dremmil to clean up the spot to be jb welded, it will stick better.
dont let your jb weld go much below the "adjustment button" or you will have to remove it.
you've got to loosen the muffler to get to that shock.
swap sides when you put it back on, the shock i had with no gas was the muffler side. it cant hurt to give it a rest from the heat.
