Maybe I’m stating the obvious, but haven’t heard anyone mention, did you check to see the high speed jet is clean and make sure that needle is set correctly? That one on a JW usually is between 1/3-2/3rds turn out. If you’re fuel system was dirty, chances are some of that got trapped in the high speed jet, which supplies the lionshare of fuel to the motor.
Make sure your float is set right too…level with the upper carb casting when upside down. Make sure you’re testing it with the air silencer and mesh screen on it. Some of these motors just won’t run right without those two things in place (ran into one of these about a month ago…whereas previously they all ran fine without the screen or silencer in place).
Agree with FrankR…that spark should be AT MINIMUM 1/4 inch bright blue spark on an air-gap tester. It’ll run with 1/16 – 1/8th spark, but 1/4- 1/2 inch is the right way it should be.
