No idea how many G4/LM carbs I have here but most of them have no needles or primer caps because I'm constantly ratting them to find one that works. Too difficult to fit a G3 to the existing manifold and the G4 and LM are a fantastic carby once modified apart from the float needle. I'm always on the lookout for full crank barrels with G4/LM manifolds so I can set they up with the plastic carby. Millions of these carbs out there, needle is the only issue with them
