Ring job

[bristol@coastnet.com (JIM WALTERS)]

Tim: Black, black smoke is not an indication that you 
have blown oil rings, it means that your carb is 
flooding or the automatic choke is stuck on, especially
if it's a 75-80 MGB with a water operated choke. These
are notorious for sticking. If your oil rings were 
blown your engine would be pushing BLUE smoke. Jim.
