Your explaination should say make adjust slowly, no more that 1/4 turn at a time. Most people overadjust and result in a low float level.

You can only do that adjustment method on the primary side if its a vacuum secondaries. If its mechanical secondaries you really have to blip the throttle a few times b/4 doing any adjustment on sec float level

For the secondaries, remove one of the lower screws for a few seconds to drain some of the gas. When its restarted, if gas flows out of the secondary hole, adjust it down a little. Repeat.

You may have dirt in the primary needle and seat area. Remove and inspect. Clean or replace (if necessary or really old).

Good tip you mentioned was go for a ride. Come back and check levels again.
