layfin : Had the oil been drained before lay-up ? my old BSA C15 used to "wet-sump" after standing even a few weeks . ie the oil all drained into the sump , and fired the whole lot up into the cylinder head upon start-up . This overloaded the return pipe into the oil tank and consequently some would come out of the breather pipe as well . The C15 system was virtually identical to my old 3TA .
I used to push the oil around using the kick-start , with ignition off , to get some out of the sump , before firing it up .
You may already know this , but it sounds familiar .

Fuck me - a sensible, hopefully helpful reply! You sure your on the right forum HG? :wink:

 

:biggrin: Its an easy fix if its right brybrem , I `ve had the contents of the sump on the garage floor a couple of times , I can tell you . Hope it works layfin :HG: :biggrin:

 

Won`t do any harm Chris .
If thats the issue , it means draining it when you lay it up .
PS . At least you know the oil pump is OK .
