I have 83 GL, EA81 with Carter-Weber. The 2ndary barrel is not flowing any gas. When I rev up to high RPM manually, only the 1st is flowing gas. I can manually open the secondary with a screw driver, gas flows and engine revs.
I don't know enough about these carbs...when should the 2nd open? I can't seem to get it to flow when revving up in the garage.
I'm having stalling/sputtering problems and I think this may be it.
Wondering if the mechanics are not working. Attached a picture.
