Just checking you've not confused the main jet and emulsion tube with the pilot jet, handy thread here http://foc-u.co.uk/index.php?topic=23023.0 thanks to BBrown1664 
. Also check the pilot air screw jet, it sits right at the front of the carb mouth engine side and at a right angle to the pilot screw, they get blocked/restricted by gum. Use a long strand of nylon from a dust pan brush or broom or any non metallic rod to clear the hole and the air bleed circuit, back into the carb body, it will pop out of the small hole in the main air flow camber.
