Knackered oil pump...BFP11R3...solenoid valve kerput...
horrible nasty burners, minor 1's, do yourself a favour and bin it and buy a bentone nu-way ST35 burner...will save you many £££'s in repair bills.
and in oil to think of it!
oh yeah...go check your oil filters at the tank or in-line are clean!! if you have an atkinson tank valve, the filter is the bowl underneath it, and there are others with a sneaky 19mm headed bolt underneath the red shut off knob...with a gauze filter inside that gets gunged up big style!!
