Carb mysteries: Just a little squirt?

[@nicholasfulford209]

Hello Ivan, my uncle was the late Ted Recce who’s father owned Recce engineering located at Carshalton Beeches in Surrey , I used to have a Fish carburettor on my mini, they did a lot of camshafts for the F1 cosworth engines DFV possibly in that era 👍

[@Dazsvintagestuff]

You did very well to get through a talk on carburettors without mentioning Miss Shilling's orifice.

[@rebekahfrench5747]

Nothing like a box full of carbys from earliest days of motoring history to keep you amused on a rainy day.. 😂😂

[@nigelsears7191]

nothing better on a rainy sunday than a video from shed racing thanks as always

[@g0fvt]

The Reece-Fish is a very clever carburetor, the tapered groove is called a weir, it feeds the butterfly spindle, the design also forms an accelerator pump as well as doing the metering. I think they were popular with tuned air-cooled VWs. I think a derivative was the Minnow-Fish.

[@danielboughton3624]

Seems like Vizard wrote a bit on that. Been a long time so going from memory and I have more than one of his books.

[@g0fvt]

@@danielboughton3624 I think he might have mentioned them in "How to Modify Your Mini". I had one for a while on a Ford pre-crossflow.

[@bryduhbikeguy]

I stopped the video,as he was reassembling it, to say the same thing.TY.

[@johngibson3837]

​@@g0fvtI remember reading about the fish carbs in one of Vizards books on mini engine's

[@danielboughton3624]

@@g0fvt You are right, on page 32 there is a diagram. Those pages are getting a bit yellowed.

[@johnlewin5277]

I believe the great David Visard was quite a fan of Reece Fishe carburettors, Keep up the brilliant shed racing! I could spend hours listening to you.

[@jonathangehman4005]

What a pleasant way to spend a bit of time on a Sunday morning. Thanks, Susi and Ivan!

[@ThomasMulhall]

Marvelous video, thank you both. My favourite is that DCOE Bolognese. I have had them on a few Fiats, and now 3 of them on an Aston 6 engine. Love the throttle response and the noise. Also, there's that slight petrol vapour smell that is delightful. Bless you, and thank you, Tom

[@Fintoman]

Lovely education on old carbs delivered by two lovely people.

[@chrisval78]

You're so lucky to have those historic SU carbs. When i worked for SU, i saw some in the stores, but didn't have a clue what they were fitted to. I should have bought the damned things when they closed the service dept.

[@georgerobartes2008]

The Reece Fish and Reece Minnow ( a smaller version ) were metered slot type that fed fuel through the throttle shaft via a travelling jet that followed a variable width slot . The Wal Phillips Fuel Injector built in North Street Romford Essex , was based on a rotating orifice , similar to a ball type stop valve that was linked to the throttle shaft . Adjustment was made by changing the size of the orifice and length of the link between the throttle shaft and the valve . The Wal Philips did not have a float chamber like the Reece carburettors but simply relied on gravity fuel feed from the petrol tank . For Lucas Kugelfischer injection systems contact Lucas Development in Norwich Norfolk.

[@philhermetic]

On the Amal carb there would be a cutout in the gasket to open that port to the vacum in the inlet. Phil

[@benork4430]

You remind me of my grandfather, he was my hero, he seemed to know everything about cars and I helped him or he let me act like I was helping, thanks for your knowledge and your beautiful personality

[@MrRobster1234]

Ivan, you are correct that those twin-choke S.U.'s were on the twin cam, Triumph engines. TRS I believe AKA "Sabrina".

[@oldcars5547720]

Suzie has raised the quality of these videos immensely. It is interesting to compare how different all of these carburetors are from those designed for American engines. I have long thought about putting a pair of Weber side draft carburetors on my 1955 Chevrolet six cylinder but nobody has ever made an appropriate manifold. It is fed by a Rochester single barrel downdraft with an automatic choke. You can fit two or three of these carbs on the engine with aftermarket manifolds but they are expensive.

[@lynnesarc6461]

Hi from Hervey Bay Australia, love all the information on all the various carbys, I remember my dad used Amals on a six cylinder Holden engined midget, went well for a while. Keep up the great work.

[@ramseybarber8312]

Ivan Wal Philips was the mechanic at Wembley Speedway Team he made a Injector/ carburetter for the speedway engines it operated with a pressurized fuel tank .

[@unpob]

Thank you Suzy and Ivan

[@A2CVMAN]

Ivan inquitisive and still learning, what the UK needs, thanks Ivan and Suzy.

[@retromechanicalengineer]

It's raining over this side too, so what better than to indulge in the company of knowledgeable Ivan and the fabulous Suzie? Dean.

[@danielboughton3624]

On the SU you can change the needle, the spring, and the dashpot oil as well as change the height of the float and the well relative to the deck. In addition you can machine the dashpot damper down or change the leading edge taper all to mess about with how fast it comes up and where it sits on the needle and so forth. A lot of knobs to turn but also very forgiving.

[@paulboyle6857]

There was also the Minnow carb devised by a guy called Bob Henderson who raced a Mini Traveller so equiped & it went very well;I think they only had about two moving parts!

[@thephilpott2194]

If memory serves correct Edd China may know of a company that refurbs Kugelfischer systems (or at least supplies the recon kits)

[@philhermetic]

The bugatti carb is the similar metering flap to the Bosch. K-jetronic fuel injection system! Phil

[@gazzafloss]

Another great session in the Shed with the Shed Racing team, what a great way to spend some time. I'm an SU carb fan, love them, understand them, but they have their issues. It's interesting Ivan, all those variants of the Webber carburetors, but I guess they are the carb company of choice to Italian auto makers just as Holley, Rochester, Stromberg, Carter etc were to the American auto makers. For good starting and smooth running, thank goodness for fuel injection, complex yes, but only for us old boys.

[@thamesmud]

Wall Phillips carb was a flat slide device, used to be marketed as "fuel injection" but it worked the same way as an Amal as far as I know. They were quite popular in speedy and grass track racing, I have an idea that Alf Hagon was their agent.

[@dave-d]

Priceless. Good timing Ivan. I just spent two days trying to decipher a pair of 1997 Mikuni CV carbs from a motorcycle and still have a lot to learn! Every day is a school day. Keep em coming mate. Always a pleasure to watch. Thank you.

[@danielboughton3624]

I don't know about the 70's BMW's but in general the first check for motronic is the coolant temp. sensor that tells the ECU what the engine temperature is. Another check would be fuel pressure. Sometimes the pressure regulator gets stuck and you end up with too much pressure at idle (or too little). On early/mid 80's BWMs it is vacuum controlled and on the end of the fuel rail. On the early/mid 80's BMWs I recall there is also an air compensation valve to leak air at idle to lean it out. I don't know if the early ones had those.

[@gordonmcgregor6431]

It’s a Kugelfischer system on that BMW which is mechanical no electrikery you need a measurement device to set the pump up and a LOT of patience. Sounds like the pump needs an overhaul and setting up correctly after that they generally run very well

[@jamesadair9711]

I think Brown & Barlow were taken over by Amal. Enjoying all the videos very much, if you ever get time,could you do a min or two about that lovely little model loco & tender in the cabinet one day? Kind regards.

[@johnrussell5245]

I asked about that awhile back. It was made by Ivan's dad during the war.

[@selsdon7073]

308 cambelts are easy Ivan, just jack it up, remove the offside rear wheel and wheel arch liner and you have all of the access you need to do the belts and tensioners 😊

[@JorgeFernandez-uc9qb]

That is a nice collection you have there. Thanks for the lesson on them. Cheers!

[@wilsonlaidlaw]

That is the first time I have seen a pair of twin choke SU's since my brother and I went to Dicksons of Perth to collect our mother's new Morris Mini Cooper in 1961. They were on a 2 litre Coventry Climax FPF engine in a Cooper T39 Bobtail. Apparently it had been used in European Hill Climbs and the SU's coped better with altitude than the Webers. Not quite sure why, as the Webers on our Aston Martin DB4GTZ coped perfectly with going over Independence Pass in Colorado on the Colorado Grand Rally , which is just over 12,000 feet.

[@philhermetic]

It was marketed as the Wal Phillips fuel injector, often fitted to motorcycles. Ran lumpy att liw revs but really good performance at the top end, the Reece fish was connected to wal phillips, but cant remember the connection! Phil

[@philhermetic]

The reece fish and the WalPhillips used a similar method of using a variable orifice to meter fuel. The wal phillips was a simplified version of the Reece without a float chamber. As far as i can find this was the only connection. I have been down a carb rabbit hole for a couple of hours! Phil

[@malcolmtill]

I used a Wahl Phillips fuel inject on my Lambretta with a modified SU float bowl on which I could vary the height of the fuel bowl relative to the injector

[@philhermetic]

@@malcolmtill that sounds interesting, they did piss fuel out if the engine failed to start!

[@malcolmtill]

@@philhermetic Oh yes they did. I went to a 32mm amal monoblock after, much more reliable

great Video Ivan Suzy

[@Rich13-60]

Fantastic video Ivan and Suzie. If you ever wish to sell those twin choke , twin SU's, I have a Triumph engine just waiting for those, would be fitting two twin 40 webers otherwise. Prefer SU's for originality though.

[@grantbaker3336]

The Wal Phillips Injector as it was called had no float chamber and the fuel was simply gravity fed, fuel metering was achieved by rotating a shaft with a hole in it that lined up with a hole drilled through the shafts bush, turning the shaft altered the effective diameter of the hole thereby metering the fuel, this shaft had an outside linkage connected to a butterfly by altering the length of the linkage and the length of the arm on the metering spindle which were both made from threaded rod it was theoretically possible to achieve a perfect mixture across the range.

[@bmc-freak2983]

S.U - verdens bedste karburator :-)

[@glynluff2595]

I think Wal Phillips was a fuel and also a water injector. The fish carb I think took the fuel from the taper and fed it through the holes in the butterfly. I seem to recall many years ago being told about these for sprint motorcycles by a friend now long dead.

[@robertrawlings]

Ivan when you can get round to it tell me about your locomotive on the shelf behind you , id be interested to know as its always there 😊

[@stevem7868-y4l]

If i have 10% of Ivans energy, when i reach his age, then i will be very happy, a great vid on old school fuel to air metering Also, i had a Fish carb on a Bsa single, think it was a 250, and its was horrible to drive, no progression, just full or nothing, like a switch

[@shedbythetracks]

Well... I think I kept up with it... sort of. Cheers from my shed

Well done Ivan very knowledgable and informative the proper engineering not like today stuff electronic brain washing

[@paradiselost9946]

24:20... go back even further... older... edwardian... victorian even. "air compensation valves". the key to how emulsion tubes work, really. and CV/SU carbs. air speed through the venturi is based on RPM, and throttle setting. the suction on the jet is not linear with air speed. so as an engine unloads, and picks up speed from a given throttle setting , the mixture gets richer... and as load builds, it slows down.. mixture leans out. the exact opposite of what is needed. so the air compensation valve is an intentional air leak in the manifold after the venturi. add extra air after the jet to counteract the increased air speed through the venturi, and maintain the required mixture. from there, flip the idea, and let air leak through the fuel system instead, and lean it out that way... the emulsion tube. and that has its two variants...webers using air bleed jets, and motorbike carbs like mikuni etc tending to use a pitot tube. both give the same end result. as RPM builds, the fuel level around the emulsion tube lowers, uncovering more holes, and proportionally more air is bled through as the suction increases...

[@samrodian919]

A very nice description of how it works. Thank you!

[@cliveturner4788]

freddy dixon said carburation is just a controlled fuel leak and what about miss shillings orifice ( of spitfire fame )😂

[@lancerbiker5263]

Many say fuel injection caused the extinction of DIY mechanics.

[@emmajacobs5575]

Yes and no - with production engines’ electronics, you can’t do much, but with modern standalone ECUs, instead of Ivan’s can of WD40, you just plug in your laptop and squirt electrons down the different holes to achieve the desired effect!
