This is the Zenith Stromberg carb from my MG. I found out that it has more bits in the single carb than the 650 has in two carbs.
Bad part is that after attempting to adjust the carb it seems to run about the exact same as it did before I tore it apart and even though the automatic water choke is functioning as it should I still can't get a high idle when it is cold????????? So I'm glad you guys had fun, wish I had come rather than do a bunch of wrenching with no results.
