I recently took my 75 Gl1000 to the shop to have them sink carbs and check timing. Bike was sluggish on takeoff. I get bike back and she has no power. They say it is in the carbs so I tear them apart, dip them in chemdip and verify all my jets are clean. Put new orings in and she wont run right. Adjusted the Idle air acrew out 1 3/8 turns and she will only run choked and that is it shut it off she dies. any ideas?
