Thanks for resurrecting this thread. I am in need of advice or assistance from anyone with K&B engines.
I have a K&B Sportster .65 that a friend gave it to me to rebuild and it's mostly in good shape. My problem is with the Needle Valve. It will not thread into the Spraybar. It is as though the HSN is just a mil or two too large to fit in. I am afraid that if I force it in it's going to gall.
I've emailed Meecoa to ask if I could send both pieces in, so that they could find a part that would fit one or the other, but so far, no reply from them.
Has anyone else run across a situation like this???
Bob
