the carby used on 6 cylinder series 3s and all v8s in australia was the
zenith-stromberg 175cd, not 150. i can only assume it was te same in UK. The
175 is 1 3/4 inch while the 150 is 1 1/2 inch. it may be that the mixer will
be a tad small for the 175, or do both those stromberg models have an
identical bolt pattern on the filter side?

There are 2 spare 175CD gas mixers sitting here doing nothing (other than
gathering dust...) that could be anyone's for a reasonable offer...?

I think I actually meant CD175 anyway!. My other car had 150's on.

Lee_d borrowed my spare carb and fitted it straight onto his 6 pot, so
it must be a 175.

Yes, that's why Martyn says it sounds so good. Its running really well.

Jealous ? I don't know, in a straight line, or over a limited angle of

The figures I had were NOT from that run - when I dragged a trailer with
a Porsche scrapper on the back the week after, I got EIGHT to the gallon.

Would I really notice a binding brake on a 9X16 ?

Looking for ideas.

Whatever - none of the LPG guys "standard" SU or Stromberg fitting
fitted whatever REME fitted on Bob !

A photo of the carbs would help I guess.

The more I read the more I'm thinking rolling road. Your going to be chasing
your tail for a long time otherwise.

I'd be suspicious of anything non standard fitted. Running well and Sounding
good are not really good ways to tell if all is well. It sounded good on the
sound bite on Mike Derricks web site and still sounded good at the camp
site. It's clearly been tinkered with a bit between IYSWIM. Did you make the
new mixers such that they don't restrict the air flow and if so could this
actually be part of the problem poor mixing? What does it do to the gallon
on Petrol? This should give a indication as to where to start looking, if it
was any more than 10% better I'd still be looking hard at the gas setup.

Have you compensated for the timing on LPG?

Is the gas you buy tending to be from the same outlet? Could be crap gas or
a pump that needs calibrating.

He was tuned up professionally, about 2 months ago, on a 5 gas analyser
at Pioneer Autogas in Rochdale, he was "perfect" then, at idle and "at
revs", but that's not on a rolling road. The injector have an aperture
of around 1.25", from memory.

Its so long since I ran him on petrol I can't say.

> Have you compensated for the timing on LPG?
No, and I'll look at that when I do the ignition system. Some say it
doesn't matter, some say it does. What do you reckon ?

Nope, I've been all over. MOST of the figures have been steady 50 MPH
numbers too.

Thanks for all the ideas guys !

Well if the engines get hotter when the timing aint right then that heat has
to come from somewhere so I'd say yes it does matter.

I know a fraction out when running on 7 cylinders make the difference
between Morph being a Hill mucher or a road side Cafe. Can't wait to get him
going again :0)

Hi Sean,you a bit of an expert on101s? Toying with the idea of an ambulance camper sometime in the future.No doubt fuel is the big stumbling point here.Do you know anyone whoes converted one to diesel & if so what kind of engine type/transmission option/diff ratio combination would give a reasonable result? I have kept a pair of 2.82:1 Kam diffs lurking down the back of the shed...just in case! mucky`un.

LPG goes better if the timing is advanced slightly, about 3 degrees,
compared to petrol, but it's not critical.

Well, he's not running on 7 according to expert ears, so its got to be
the timing that gets checked out next.

Thanks for the timing info.

Thanks!. a nice read there. I hope you continue to update it - it'll
give me more motivation!.
I bought my ambi about the same time as Tim bought his and his is
doing better than mine :(

I've just advanced the timing on my car (running on LPG since earlier
this week) and its made an improvement.
I went from 15 btdc to about 20 (book says 18btdc for 4 star juice).

I've also disconnected the vacuum advance as it was recommended. Might
put it back on later to see what difference it makes, but the car is
currently going really well.
I have a slight misfire when it gets hottest, but i'm hoping this si
down to the plugs and leads which i need to adjust and replace.

Good point - but it was doing pretty well before then too!

Mines even gone mouldy :( (my drive isnt flat and it drains down one
corner when it rains)
