Update.
Things aren't really much better and I'm still having issues keeping all the parts we sell in stock. The good news is that there are only a few items that so far and NLA and have been on backorder over 6 months.
This includes the excellent slotted metric idle mixture screws for the 1979 and later carburetors. I keep checking on them, and am told that they are still at least a month out.
If you have ordered a rebuild kit, be patient, USPS is also being very unreliable these days and longer than normal delays in delivery are common........Cliff
