Check compression?
Checkvalve clearances and condition of valve train?
I had experienced similar symptoms with an MGB. It was a clogged fuel filter
starving the carbs, but it sounds like you already checked those parts.

Help - the Wisco driving season is finally here and my Bugeye is 'missing' in
action.
I've got a terrible miss at medium throttle and low speed under load. When I
put it into second it just stutters. At higher speeds it still doesn't wind
out. This all started last Autumn. When I rev it in the garage I can hear the
hint of a miss. After test drives, sometimes one or more plugs are sooty,
often times all are clean. It idles well.
I didn't make any changes before this happened. Details: stock 1275, twin HS2s
w/ AAC needles and blue springs, Facet fuel pump with Holley regulator,
Mallory dual point dizzy and coil, new wires, NGK 6ES plugs.
I get a good steady spark at all cylinders per timing light. Timing is good;
advance is good. I checked the carbs many times, also switched and switched
out suction discs and chambers. I checked the jets, moved the flats in and
out. Tried different levels of dashpot oil (10W). I checked the floats.
What am I 'missing' here? Any suggestions would be greatly appreciated. Hurry
- the Wisco driving season isn't that long!
