I have an old pirkins 3 cylinder engine. When it gets hot it keeps cutting out but not sure why. It seems like a fuel problem but can't find anything obvious. Any suggestions much appreciated

Not sure it's for a friend. It's an old industrial one in a Barbour green tarmac layer made somewhere about 70's
It'll not be a P3 then.Likely an AD3.152 as in a MF 135. Will it start again when cold or does it need bled? Have you loosened the tank cap-- is the breather clear? Could it be drawing air?Try a gravity fuel feed from a drum.
I have a 135 that would stop when hot. No problems any other time. Injector pump was checked out twice,new lift pump,tank washed out,new pipes and all filters cleaned and still it would die only when hot. Removed the filter head hoping to find a crack that perhaps was opening due to the heat but no. Nothing.Refitted it and it has been fine since.That was 2 years ago. Still don't know what was wrong. However, if you're sure the filters are spotless,including the one inside the inlet end of the inj pump(if it's still there),try pouring cold water over the pump. It's possible the pump could be worn enough that when the workings get hot enough and expand,pressures are lost. Cold water will contract the parts again. Worth a try.

Starts fine when cold. Just cuts out when gets hot then you have to leave it for 20 mins before it starts again.

Some Stihl two-stroke oil mixed in the diesel will help.

Have you checked the valve clearances?
Tight tappets could cause power issues when warm.

i add oil to the diesel on a massey 8250 with a bosh inline pump if i forget it will not start when the engine is hot add oil no problems at all
I put 5 litres into the full tanks of the 7840, which would have been into about 215 litres of diesel,or thereabouts. Some say ATF isn't ideal as it isn't designed for burning and perhaps 2 stroke oil will do the same thing(??) but I've had no problems using it.
