Ive also gone back over a number of comments in this thread including some of the
discussions my late father was having with another Bedford Motorhome user in the
UK who had similar problems (although his seemed definitely related to leaking manifolds)
see this thread if your interested  ::)

http://oldholden.com/node/27503#comment-110045

any way... I had another look at this attached article on running dual fuels i.e. Petrol and LPG

http://www.acl.com.au/web/acl00056.nsf/0/359683e8a538a3e64a2566c0007bb33e?OpenDocument

It seems that my dads mechanical lever that changes the advance from 6 degrees to 12 degrees
only really helps the engine at low RPM because according to the article LPG requires less advance
at higher RPMs so the lever is really only a compromise as best...the best thing would be to invest in a dual
graph distributor...like the Jaycar electronic Kit one mentioned earlier in this post.

Or an expensive USA MSD electronic distributor with Dual curve settings.

In the meantime I figure its best to decide what fuel I will run on most and tune for that.
(Most likely LPG as its cheaper and has the higher octane so theoretically more power  :)

Something to think about for sure... ;)

cheers

check alternator by first checking voltage across battery with engine off. then start engine and measure again. if your alternator is charging then the reading should be considerably higher even at idle (13-14 volts)

when measuring the + voltage to your coil, ground  the negative somewhere on the block and not the negative side of the coil. then the meter wont fluctuate like it is

YEah I will check the battery and the alternator tomorrow as you have suggested.

The negative side of the meter is connected to the engine Block near the earth strap
so I dont know why I get the intermitant or flickering readings  ???  go figure...its a mystery  :-\

cheers

Hey fellas

Thought I should give you all a bit of an update.

I seem to have resolved the problems with the van now performing like her old self.
Thanks for everyones input and continued interest.

As they say in show biz "Timing is every thing" and it seemed this was the issue with my beddie
getting the timing right for LPG and then for ULP.

I have taken her for a drive and got to test the bag tent I scored on ebay for only $400

see the photos below

Next I need to source and fit a new balljoint for the front left wheel assembly  any one know
the best place to purchase these?

Hey Worby love that tent is it free standing or do you have to attach it to the van I want something like that so I can leave erected at caravan parks so no one pinches my spot when I go out sightseeing in the camper It's a pain in the ass when you come back & someone has nicked your spot Cheers Reid

Looking for an annexe myself - they used to be called van tents and with the setup I used to have you could mount the kitchen on the cargo door and cook in the "tunnel".

As restoreid says they're ideal for marking your territory  ;D and leaving some stuff in while sightseeing.

This annex tent Is known as a bag tent because it is stored in a long vinyl bag that is attached in the channel on the side of the van.

So you can't leave it un attached to the van...sorry, :-\

Cheers
