Is your carb like this MD38? I went thru this one, but don’t really remember a packing,
but perhaps there was.
It’s hard to make small leather washers with punches, but that’s always an option
to try to make your own.
I was taught a trick back in the 70’s, when in a pinch, use common string,
wrap it around the needle, tighten the packing nut, and you’re mowing
lawn again!
Prepare to be boarded!
