>My relatively new (to me) '57 MGA 1500 was running perfectly until one day

change. Car starts and idles fine, but misses and backfires on
acceleration, has no power, and seems to be running hot. Points seem OK,
new plug wires and plugs. Any ideas?
Check to see if the vacuum diaphram actually holds a vacuum. Sounds a lot
like no vacuum advance. Also be sure there's oil in the carb dashpots.
Check the timing again. If all else fails, do a compression check and call
back.
