Help, I took my 2 HP carb apart to clean it and now I don't know how to re-align the Carburator Primer Cam and the Carburator adjusting lever which attach to the carb adjusting needle. I know I should have marked them before loosening them. Is there a basic set up I can follow to get it close enough to allow starting. Thanks, Roscoef. PS I have a parts list but no repair manual
