was running fine but stoped as though no fuel, plenty of fuel.
Renewed delivery pipe from gas tank to carb still only runs for a few seconds on idle , dies instantly under throttle.

The Walbro carb on the Multitrim 16 does not have a pump as such but relies on fuel delivery from the vacuum formed when the piston sucks fuel through the carburettor. The probable cause is the diaphram under the cover plate with four screws. A replacement kit costs a few £/$. Take off the carb to verify the carb number which should be stamped into the body. Get a carb rebuild kit on line or from your local dealer.
