carby/petrol

[TREV65]

Hi,
I have surfed this site and have not come across any info on chokes.

Is there a kit out there to change the carby over to a manual choke setup?

I have rebuilt the motor and is 10,000 old now and has to have the pedal held down slightly on start up on a cold morning.... everything else runs well.

Also,
Fuel guage on dash only starts to read when half full to empty, I have been told it is a common problem but cannot offer a solution to fix it.

I need a new tank as well as mine has a pin hole and dents in it from previous owner, should I go a 70li or stick to original? even the aftermarket ones need the original sender, is there a new style and guage on offer from VDO etc that would do a proper job?

Regards

manual choke can be done, but a few of us were so fed up with the dam carby we replaced it with a weber =)

do a search for "fuel sender" theres info on fixing it around here somewhere - perhaps even in the bible its that common.

original tank will be the cheapest option too.. but if you have coin to spare a 70L tank would come in handy (or perhaps its time for LPG conversion?)

[RockHopper]

Maybe give your choke flap and linkages a good going over with carb cleaner. If that fails, fast idle probably just needs to be set properly

[lay80n]

Regarding your fuel sender issues, check your earths, as these are usually the culprit. If this does not fix it, drop the tank and remove the sender and check that it does not go open circuit during its full arm cycle.

To swap the choke over to manual you would be looking at making the parts yourself. Not too hard. Even a basic hand throttle would sufice if you just wanted it to run without having to put pressure on the throttle pedal constantly. I dont think there is a kit though. I just let my Haltech sort it out

You can buy a new sender from bbm rick for about $50.oo
also go to pep's and get a universal choke kit
if you ring the 4x4 wreckers up the bay
you can get a good tank around $100.00

Hi,
All very good advise has been given,

who is BBM?

any particular wreckers? the one here at Lemon Tree passage has not got any wrecked zooks left.

and
is gas worth while on a zook, even if I get rid of the petrol tank, would I have enough room underneath for a largeer tank (gas)? I would not like to lose the seat in the back for when my kids visit.

I'm not sure how much it holds, but you should be able to get a donut type lpg tank to fit under the sierra. Am considering it myself, if I can get a 50 litre tank to fit under there, but I just gotta find a bit more time to do a little research

[over land 4x4]

i was looking at gas for my zook and i found out that the rover (the older 4x4 ones) has a spot in there boot space that thay put 2 small tanks into i dont know tha size of the tanks but i know that thay will fit in nice
you will also need to look at a small fuel tank if you run out of gas it could be a bit hard to fill a jerrycan with gas

you wont get a donut tank in or any other tank that i have found to fit in the fule tanks spot with out a lot of work. There are some new flat tanks i have herd about thay may fit but youll need to find one and see how big thay are


i hope that will help

there was a thread on LPG where someone suggested running a series of scuba style tanks in series under the zuk, which would help the space issue.

me unfortuanately no one has the needed dimensions certified at the moment

I got the idea from the 3 tanks that are welded together for falcons, total was 75lts and each cylinder was 84cms long and approx 22cm diameter (approx 20 usable litres?)

Maybe a problem even with a body lift they would (if available indvidually) stick a little lower than the chassis rails (well people fab up bash plates and rock sliders)

Other ideas are to move the factory muffler closer to the cat and a small resonater snug against the chasis rail giving you a much wider room for a van size cylinder.

A small 5lt auxilary petrol tank somewhere would get you out of tight spots and limp to the servo (filling up every 30-40kms). If you manage your fuel use properly you shouldn't have to resort to it


Other possibility is an outboard fuel tank feeding into a small surge tank.
The car fuel pump can circulate the excess petrol back into the 'surge tank'and the outboard feeds its by gravity when it runs low.

Very illegal set up 'not to be used on public roads' but sure beats the hell out of the other option i have read as an anecdote on this forum.

If I was to go gas, it would be solely gas...... I had a bad experience with mixed settings back with my old 69 ZB Fairlane, I learnt that you had to tune the car to either petrol or gas.... never found a happy medium between the two. on gas it used 22-25 per hundred and petrol was around 18-20.... took gas off altogether and rebuilt original carby and got a constant 12li per 100k. better power and cleaner running.

[Santos]

i was talking about a straight gas set up, the petrol was just a limp mode. Tune it to gas nd if you ever get stuck somewhere have a little petrol to get you out of trouble.

Still with programable ignition i don't thinks it would be that hard to tune for both anymore

I will never have gas again, too expensive.

Mate owns 24 taxis, when fuel is more than 40% the price of petrol, they go petrol. All late model fords.

I recon gas is useless, had it on a few V8s and power loss was substantial, unless you pour huge volumes of gas in, and, hard to take a cuppla jerrys of gas with you on a long run.

gas is every bit as good as petrol when tuned rigt, especially on a 4wd, as you can put your car on any angle and it will still run with no flodding or starving issues. I had gas on one of my older patrols and it ran like a dream on gas and petrol. If I had it on my last patrol, I probably wouldn't of sold it.

[david123]

I used to have a worked big block in a 4wd, many dyno runs trying to get some form of decent power and economy on gas, bout 4mpg, did go like the powers, but so very expensive. Went back to petrol, 12mpg, and a lot more power. Torque.

When gas was 27c a liter, no drama, but as it rose dramaticly, the economy of gas went south very quickly.

When you do the sums, gas, no thanks. Not to pay for the change anyway.

[zook4fun]

then you must of had a very bad set up for the gas. did you change the dizzy curve at all?

my last gas car (old kingswood ute 308) was a pig on petrol, i was using $120- $160 week for fuel got the gas set up right and was using $80 a week for the same k's. this was last year.

i'm about to put the wifes range rover on gas and i'm garenteed a 5% power lost and 10% more fuel use, its all dyno tuned and tested. i'm going gas injection not the old mixer set up witch is what the kingswood was.

[Gwagensteve]

Good luck - I converted a 91 rangie to dual fuel. Big mistake. No range, poor running on petrol, poor gas economy, then a gas backfire blew our the airflow meter so it ran even worse on petrol.....

Gas is for forklifts and BBQ's.

[zook4fun]

was it a mixer or gas injection? gas normaly only back fires when running way to rich, poeple never use the primer then wonder why the car back fires.

gas injection is just like fuel injection, different computer and everything.

[Gwagensteve]

Mixer.

Professional, Dyno tuned, install at a leading LPG converter in Melb, conversion less than 6 months old, engine had been running for 1 hour when it blew black on a steady throttle at about 80 km/h

Due to the small gas capacity rangies allow I couldn't run straight gas.

Steve.

[zook4fun]

i would of turned around and went back, they shouldn't back fire just out of the box.

i'm going a small donnut tank where the spare wheel goes. its just to bring the cost of running it down as the mrs drives it to work every day.

the gas computer is hooked into the std computer and when gas is on makes it think its running on fuel but the gas computer is running the car.

i'd love to put on of these set ups in a sierra but it would be worth more than the car i'm building up now.

[Gwagensteve]

It was just one more thing in a massive list of ongoing problems with the RR, most of which I was doing a commute that was killing it.

We traded it very shortly afterwards on a road car, or it would have gone back.
