It's been a whole lot of years since I had my head under the hood of a
toadster, but as I recall the carbs were Hitachi knock offs of SU's. Does
your car have evap canister (charoal canister?) If the evap system is
screwed up a slug of fuel can travel through the evap line and into the
engine flooding it. I had a car that did that once. As Paul pointed out, if
the tach drops like a rock, think electrical.
Good luck
