OK, now started into the first choke assy. The choke locking washing under the nut was not bent over. Notes with AUD623R show 2 orings in the choke, but the Burlen notes from the web say late models had 2 Orings and no gasket . The kit has one O ring that looks correct for the choke body, and a small one that I cant see a home for, so far. There was no gasket on the choke , but one is supplied. Under the end cap of the choke shaft there was a small (~4mm ID) Oring that I cant see being effective - not clamped by the cap, loose on the shaft. Should one of the spindle seals (3 supplied) go in here? Maybe this was the source of the visible small leak, rather than an internal Oring failure, but what was
making it run rich as?
thanks.
