Facon Weber conversion

I was talking to a bloke this morning who wants to get rid of the 350 Holley on his 186 LC Torana.
Can someone tell me what model Falcon the Weber carbies are from that go well on a red six?
The model number of the Weber.
Also, where can he get an adapter to put the Weber on a 350 Holley manifold?
Will the Ford air filter fit under the bonnet in an LC?
Should he paint the air filter gold?
Thanks,
David

XE falcon had the Webber and I think it was a 36/41. It will probably still need rejetting though. Most people use a sports type cleaner and you can paint it any colour you like but gold will make it go faster.

xe and xf falcons had weber carbys. the modal name is 34adm.

the earlier ones from xe's have slightly less "bolt on" pollution and idle up solenoids etc on them, but you can remove/disable this if unwanted on the later xf ADR37 carbys. the easiest way to pick the early carb is in the primary throttle they do not have a protruding tube of approx 5mm diameter.

you need to wire up 12V switched with ignition to the idle solenoid otherwise it will not idle.

one of the daves on here was casting adaptor plates.

the falcon filter fits under the bonnet of hq's so i can't see why not under an lc lj bonnet, or if you want just cut up the base of a chrome air cleaner to the weber shape, i have done this before also.

I'm sure it was Davequey. He's moved to Bookface, but if anyone is keen to get something made up, do a search here and you should find his details. Dave's a great bloke, very approachable.

and also i have fitted quite a few of these to holdens and valiants and never had to change jetting from standard. they just work.

forgot to add they also need 12V to the electric choke, and they work really well once set up right.

For what it may be worth, the XF electric choke has a power pickup directly from the alternator and it's 7 volts. I don't know if 12 volts has an adverse effect on the choke but it probably does seeing as Ford went to the trouble of having this outlet on the alternator. Has anyone here who's made the weber conversion run their choke at 12 volts and found it to be okay?
Please look at the alternator pictured left. >> http://i364.photobuc...

I think the Reason they went down this Road was to keep the Auto Choke Temperature in phase with the Engine Temperature.

If the Auto Choke was Ignition fed, and the Ignition was left on for a long time before a Cold Start was attempted, the Auto Choke would be deactivated making the Cold Start difficult.

If the Auto Choke was AC fed from the Alternator, and the Ignition was left on for a long time before a Cold Start was attempted, the Auto Choke would be activated making the Cold Start normal.

It's easy enough to fit an Ignition fed Resistance into the supply Wire to lower the Voltage down to 7 Volts.

It would work just like a Ballast Resistance.

Holdenpaedia, they're the brakes Mate.

Would prevent #any# drain on the battery too. Only powered once engine is running. Do they draw much current?

The carbs may work fine with standard jets but not ideal. A good carby place will put the sniffer on the exhaust and jet and tune it properly. Cheap insurance for best economy and smooth power delivery. A poorly jetted and tuned carb at best will waste money at worse can lean out too much under load and the rest will be history.

i think you should have worded that "but MAY not be ideal"

most people that will be fitting one of these carbs will be doing so for daily driving and economy purposes, not racing. so they are not likely to have big cams and other vacuum reducing mods that will require non standard jetting.

a stock to mild engine will have good vacuum, in which case "x" cfm of air going into the engine will require "x" amount of fuel. so whether its a ford xe falcon 250 or a 202 red 6, the fuel/air mix will be very close. in fact ford didnt even have different jets in these carbys between the 200ci and the 250ci...

whats the first thing you do with a swap meet holley?? go to box stock settings and go from there, which for 95% of engines will work best.

in my line of work i tune a lot of cars and can feel when things are wrong just by driving them, again i have never had to change jet sizes in these carbys on mild engines. good power and great economy, typical of weber - a good basic carby design plain and simple.

Idle settings and power spring are different is all.
Stock main jets (worth checking if carby is from an unknown source) are 137-primary 210-secondary.

Bit like Ben...fitted Falcon webers to all-sorts, Holdens, Grunters...even an old F135 petrol in a SWB Landcrusher....only 1 we fiddled with jet wise was on a 4 cyl Hilux....still not convinced that we had to.

I'm going to back Ben on this one too,

I Have done this conversion on a few 202's and 186's.

They have never needed re jetting. the worst I had was the accelerator pump plunger had gone hard from sitting and needed a new seal. this caused a stutter when you floored it. Changed it over and worked a treat.

they just work.

As Ben stated, 12 volt to the choke and 12 volt to the idle solenoid.

Built for comfort not for speed....

they are a carby where if they sit for very long, the diaphragms for the accelerator pump and power valve harden and split or just dont work as intended. it is best to kit them before running them on your conversion unless you have heard that particular carby running very recently.

kits are around $80 trade.
