      Amal 190 main jet for monobloc carb

      Works perfectly. There was NO main jet in the carb at al. Needle was set leanest position with correct needle jet. Installed 190 main jet, reset needle at middle position, runs perfectly. Thanks Lowbrow for prompt service!

      Main Jet 190 Concentric Carb

      Bonneville was running a little rich on fuel mixture, so sized down from 200s to a couple of 190s. She's purring like a kitten now! Thanks Lowbrow for the quick shipment and stocking what I needed.
