Hi Mick- I know how you feel. I was having ignition problems when I revived my Fury (Ford crossflow). Having tried all the usual suspects I ditched the points distributor (an Aldon special) and went electronic. I once had a problem on another crossflow where the points would stay open when warmed up. Cooled down they worked again for a while. When you are in limp mode- are all plugs firing? I have a nifty device that you touch against a lead- it's neon flashes if the lead is live. Could also check exhaust manifold heat- does a drip of oil on each pipe evaporate at the same rate. Does disconnectiing each pair of plug leads (per carb) make any difference- just in case the diaphragm on one carb has a hole.
