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.
I also replaced this gasket that had a large gap in it. how the hell does that happen? If it weren't for the bolt that holds the catalytic converter onto the exhaust pipe being completely stuck. I removed it by Dremel tool) I would not have minded so much that I had to remove the intake/exhaust manifold to get at the cover.
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.
