So far I haven't had any carburetor issues(the previous owner retrofitted a Weber carburetor for better durability and reliability) and the car has started up everytime. You have to remember at that time British Leyland(the former owners of the MG brand) was feeling the pinch from the then new emission and safety regulations just like everyone else. So in order to comply the original dual SU HS-4 carburetors were replaced with a single Zenith Stromberg carburetor. The ride height was increased by 1 inch and the rear anti-roll bar was removed on later models(which compromised some of the handling characteristics of the MGB and Midget). The BMC engines have a reputation of being bulletproof,as long as they're maintained properly(my car is living proof-37 years and 79K miles later it still runs like clockwork).
