We were somewhere around Barstow, on the edge of the desert, when the

You can claim back the duty you pay on petrol if you jump through the

Really? *Last time I dealt with this (vintage tractors) the whole non-
road petrol supply chain was being withdrawn owing to lack of demand
(and potential for abuse). You must (AFAIK) pay duty on fuel _unless_
it's dyed to make it traceable, and dyed petrol was going out of
production.

Aviation spirit used be blue, iirc, and I don't see that going out of
production. [1] There's certainly a mechanism in place for reclaiming
duty paid on that if you're going abroad with it - I would think there
would still be a demand for that, and it's essentially the same
procedure.

Hi all,

As a user of AVGAS (100/110 octane low leaded version) it is blue and
smells wonderful 8-))

There is duty *& VAT on it and currently it is anywhere from 146p/l to
170 p/l PLUS VAT. *However it is rumoured to be on the way out as the
lead contaminates the plant and so noone wants to make it as it needs a
dedicated bit of kit and is a 'small' market - hence the price!

The Swedish (I think) have got unleaded AVGAS that performs like
100/110LL (I am told) but there is no duty relief on it and is likely to
be more expensive.

And yes you can claw back duty if you 'export' it across the channel (or
as I do here just not pay it in the first place - AirBP have a system)

When I was on Shackletons AVGAS was 130/135 Octane and although it ran
very well in my Triumph T 110. It was reputed to burn out valves. It
did not effect mine so as far as I was concerned it was perfect and
very cost effective.

But I digress. I have just found that the Perkins P3 has a power of
34 hp / 1500 rpm. As it is quoted at this rpm it may well be that
this is the rpm at which it is happy. Today I found two 8 ft. pieces
of very heavy, - not channel, but I section which will be just as good
as there is plenty of room for nice fat bolts. I am in the process of
painting it a nice tasteful British Racing Green. 1 shop I have found
in Norwich has AVRs which can be adapted to any (?) alternator. The
only problem is that it is 40 quid. OUCH. Anyone got a simple
circuit?

Regards George.
