First of all, you said...
"So I changed the fluid in it with HD synthetic".
Hope you didn't install HD Syn 3 in the trans, if you did, that's not a good choice in the trans. It's not a full synthetic either and it's 20/50 MOTOR oil. There are much better choices in GEAR OIL that are better for your trans than this choice.
Now getting down to the clutch, you said...
"remove lock nut turn adjustment screw counter clockwise till it stops and turn back a 1/4 turn".
Unless I am misunderstanding you here, you are supposed to just loosen the locknut and turn the adjuster IN until it lightly seats and then back it out from there the 1/2 to 1 full turn and lock the lock nut down.
It seems as if you had the direction of the adjuster back wards. The adjustment that you do now with the engine cold will vary slightly where the clutch grabs on the handle when it is warm. It's a trial and error thing to get it exactly where you want it with the final adjustments.
