Odd hot issues

Hi All,
Looking for some things to check, for the past year I've had Dad's commer running lovely, pickering at Easter, Wales early summer, he's had many short local weekends, but recently having issues on short runs when I think its hot.

1725 petrol running a SU carb, new radiator and electric fan.

So the scenario is. Jump in starts on first crank, drive 2 miles stop for 15mins, jump starts first crank, drive 5 miles stop for 30mins, jump in starts first crank, drive 1 mile stop for 10mins, jump in starts first crank 100 yards down the road cuts out, no spluttering just dies and won't start. Leave it a good 20mins starts first crank??

When we first had the van I changed rotor arm and dizzy cap, new coil and changed the plugs.

I dont believe it's fuel evaporation as previous owner has shield the card and wrapped the manifold and rerouted the fuel line.

SU carb does have oil, so other than dizzy cap getting too hot I'm not sure where else to start looking? Any help would be hugely appreciated.

Just to add this appears to be only on short runs its happened twice on my sons graduation and once last week (the scenario above)

Cheers
Andy
 
Hi Andy, have you checked the points gap? Check that first. It seems to have the symptoms of a failing condenser so if the points are OK then replace that with one from a reputable supplier like the Distributer Doctor. If the problem persists then try a new coil.
 
I had similar problem with my 1500 petrol engine so I covered the steel fuel pipe that goes over the engine with split in the middle rubble fuel pipe put over the steel fuel line , also what sorted it for me was i cleaned the fuel filter a couple of times plus i took main jet from carburettor off and cleaned it and took top off carburettor and clean main bowl of the inside , , i was just about to put all new carburettor jets and gasket kit but since I cleaned filter and carburettor it's running like a racing car , i also have been using a lead substitute in the petrol , best of look with it
