Thanks Greg, I will keep you posted. Now to see if I can find an “O” ring kit or source?

Hobbsy, thanks for your input. I think back in the 80’s K&B had a black body Perry carb? The idle/ low speed adjustment was a large brass disc that only required “tick” one way or another to bring it in? Very sensitive. I watched many a person turn that disk sixteenth, eighth or quarter and it never idled until we could teach them to move in very tiny increments??

thanks again to all, bill
