Well Dave, if Ampcol doesn't dissolve in petrol, it might just work.
Unfortunately their site doesn't elaborate too much.
Anyone know?

I just can't seem to get it right. Well, then www.ampcolubes.com will do
this. Just don't shoot the messenger.
Cheers,
Dave
PS when in doubt, add more wine.

With all due respects guys, the Accusump will not solve the problem that we
have been addressing here.
Remember we were discussing the problem of oil being washed from the upper
sections of the cylinder walls due to over fueling during startup.
To solve this we need to add oil to the upper sections of the cylinders or
stop excess fuel getting to that area.
Accusump just pressurizes the engine's lubrication system, something that is
not really necessary because boundary lubrication will work perfectly
adequately until the pump builds up pressure.
Accusumps are used in racing to maintain pressure in extreme situations when
the engine is running at full power and the oil moves away from the oil pump
pickup.
Having run a racing 100S engine at race speeds with no oil for 10 km and
found no appreciable damage I suspect that the need for an Accusump in our
old cooking engines is serious overkill.

Here's one that Mr. Oritt has found. Thought I'd share with the list as it
looks like it would do the job too.
Dave
Many race cars and other applications use an Accusump
(http://www.accusump.com/) system to prelube the engine prior to starts. A
3 qt. unit with automatic
valve tied into your ignition switch would probably fit under your dash and
give you the rest that you need.
