But, I'm not too sure about that though, could be just heresay from somewhere I reckon.

has to be approved supplier and an approved installer here in Perth as well
under the Road Traffic Act

ok, so what happens if your Tacometric Relay dies - you wont find another the same as what you have, as it has probably been superseded
do you go for something similar (maybe 5 wires instead of 4 or vise a versa ) or pull out the whole system because its Not the same as what was fitted??????

a bit like not being allowed to replace your drag link with a Tough Dog one, because your one is bent..........

I think someone is pulling your chain


as long as it is an Approved installer (who SHOULD know what they are doing) - there is no reason for it not to be legal

must be approved by the Transport Dept. I think they do it

never heard it called bifuel - thats gay.......

Well........the guy who introduced me to that word and who called himself a trainer of LPG installers, was from Perth, WA. So, don't blame me, he's one your neighbours. :D
He claimed he's working at the alternative fuel board in WA, so if you come across the fella, say hello to him for me & tell him I don't discriminate. :D
BTW, bi community will be offended by you calling them gay. :D :bananadancing::clapping:

I reckon electric stuff like LPG safety switch & gauges, etc can be replaced by similar ones without having to go to a qualified installer. Of course, if the replacement is not compatible, then you have a problem and probably have to go to an installer to have it properly wired. I had to replace my safety switch. The original one was some crap brand and I replaced it with a PEEL safety switch, which is still going without any dramas.
What I was been told by a fella(perhaps from NSW or Queensland), that there are approved converters and a mixers or hybrid of those for each car by the alternative fuel board. Even though it can perfectly fit, just importing a brand and model that's not in the alternative fuel board's approved list won't be allowed to install on cars. Dunno about the truth of it, but that's what i was told.

Hey....hang on a sec.....you kicked my ass repeatedly in the other thread for messing with my LPG gear, now you've become liberal and calling me chicken. :groupwave::clapping:;)

BTW, if you are right, I would go back to my original idea of importing a LPG liquid sequential injection system(comes with it's own ECU) from China and either install/upgrade myself or get a fitter to do that. I was going to get a kit anyway, but couldn't find a kit that's guaranteed to work with a 6 cylinder carby engine. Plenty for 4 cylinder engines though.

as long as it is Approved by who ever does it
and
as long as it is fitted by an Approved installer

Was Cary Grant ever happy?

Gas only needs a hole so stalling on gas is a mystery atm to me.
It could be dual fuelling but only if wired incorrectly,
Isolate one fuel say gas as that is your main fuel and get it tuned for that.
Gas needs the electrics to be spot on as Big Col states leads in good condition.
spark plug of the correct heat range, timing needs to be just off pinging on fuel
because gas likes it advanced.eh keep us updated

have you NEVER watched the V8 Supercars on TV Dom....... especially when they run at Wannaroo Raceway - (Barbagallo Raceway)

considering I was running on Gas - I think 155Km per hour is quite a good score card............

Mate 155 was about all we got from the mighty HQ (not GQ). Mind you after 3 laps we couldn't stop it anyway.

Attachment 60300

thats why I never went over the 155 mark

was watching that corner coming awfully fast towards me
and my faith in my brakes was leaving in the opposite direction at the same pace

was good fun though

worst part - and an expensive lesson to learn - more power does not mean more towing grunt

but you get that

bohall, have you gotten an update for us..........????

really want to know

He's probably still recovering from last weekend's beer treatment. ;)

Since this post and a full tank of gas it has behaved . How do i post images on here ill put up a photo of my rig and engine bay

Attachment 60336Attachment 60337Attachment 60338Attachment 60339Attachment 60340 a few pics

oooohhhh
nice and red................

now, you see this here Valve -
Attachment 60343
this controls the amount of Gas going into your Carby
for some strange reason, that I could never work out, whenever the bonnet is open, people like to play with it
twist it in, or out

and then the car runs crappy

when you get it tuned, good idea to put a nice little mark on it and the pipe
so if anyone DOES play with it, at least you can get it back again

now, you see all the connectors, if they look like this -

Attachment 60345

go get your crimping machine, and whole heap of plugs, and replace every one of them
see the end of the copper - and its brownish - dirty - need to clean them - snip the end off, scrape the ends of the wire until its clean, and replace with new plug

with that "flash lube" bottle near the fire wall

sewing machine oil is just as good, and cheaper

The guy i bought her off reckons he didnt use any oil in that container ??? Lol i like the price of gas but im new to all the gear that goes with it

the oil is to help lubricate the upper cylinder, as Gas is dry - so things like Valve stem seals dry out and crack and then oil drops into the cylinders, and you burn it
and then you think your rings are shot

also helps lube the parts of the carby that would normally have liquid petrol running over them - the butterfly's etc

I've had 4 cars that were Gas powered
MK with 2.8L petrol gas
AUII dedicated Gas
GQ 4.2L carby petrol gas
GU 4.2L Diesel Gas

I do like it , but not the cost to get it fitted
lucky, all my cars were already fitted before I brought them

when I brought the MK - Gas was $0.21 per Liter
used to cost $22.00 to fill the 80L tank, and used to do about 400Kms in it per week

Yeah, I bought one of those power valves to fit in. Then realized it's too small for the LPG hose I have.
It's still sitting in the car. I can't use that power valve without any mods to it, and can't find a power valve to suit the
the Impco 300A mixer hose diameter.
Can you guys point me to the right direction where to find a one?

Hey BigCol,
How do you get "flash lube" or sewing machine oil to mix with LPG?

its setup to "dribble" into the intake
mine was on a fitting drilled and tapped into the manifold
I think it was
1 drop per 55 seconds
or something like that, cannot remember off hand

Yeah, but what is the mechanism you use for that timing?
Where do you get it from?
Thanx

works on the Vacuum from the inlet manifold

http://www.flashlube.com/en/company/...ube-works.html

As well as an upper cylinder
lubricant, I thought the
flash lube also had a lead
replacement that was first
designed to coat the
the valves in pre-unleaded
engines. I suppose it
isn't as crucial in an
unleaded engine though
as the valves are already
hardened.

So what oil should i choose lol

Hi Dom,

I suspect the IMPCO 300a has a power valve built in see item 3

http://www.teecoproducts.com/Catalog...A%20Series.pdf

If you are using a ring mixer - then you need a power valve

Hi mate,
Yes, it has both WOT and idle mixture valve adjustments. But, apparently not a good idea to try tuning it without an air/fuel mixture analyzer or O2 sensor gauge. I thought about trying it the old school carby tuning method of by ear. I haven't touched it yet. I need open up the mixer first and look for any diaphragm damage. After that, I'll get to the tuning it and see whether it needs tuning at all. Perhaps, it's better not to fix it if it ain't broken. :)
