I’ll try that, but what do you think if the hesitation persists?

The other day you ran it up to full temperature so that would suggest there's fuel , the thing that comes to mind when this hesitation happens is lack of spark at the high tension lead from the coil to the distributor [ king lead] , that and general condition of the cap and rotor ,


All changed not that long ago (4 years or 1500 miles) but worth a check again.

In situations like this i use substitution to eliminate , i tend to keep old parts when servicing and would swap over the leads to see if there was any improvement , another thought occurred to me , maybe you have a punctured fuel pressure regulator ? , this would account for the lack of fuel just as you need it to accelerate , i'm not sure i remember how you check for this but i think it involves removing a vacuum hose and sniffing for petrol but i forget , maybe someone else can remember :?
