Do you sell that bracket for the power valve cables that attaches to the YPVS servo motor? I'm in the process of building a YZR500 replica as well.

Nice!!!💖💖💖💖✨

Nicely done guys

Great partnership, both really good on your own but the two creative brains working together occasionally bouncing ideas ,looking forward to all the creations .cheers Will

Excellent stuff! On B's latest video you brought some exhaust gasket material with you - what is it please? I need a bit

What a sweet littke bike - it deserves some TLC and to be enjoyed anew 😊

now a complete La France is something Mrs Tweed put her foot down and said no way!!!.....so I have some deep trauma over these.....so if you need a hand getting it running I have a big crowbar and at least 2 large Transit batteries and heavy duty jump leads to hand.......also after 3 years of sitting in the garage the Suzuki K10P started second kick so the race is on.....

From the mild manners of the Crosley to the wild untamed ( It will be a beast in anything smaller than a Yank fire truck ) anarchy of the Lafrance. I can't help but think of Waylon Wire's V12 rat rod truck with the tartan rocker covers.

im very very excited to see and be involved in the progress on the La France.....lunatic single seater here we come!!!! 😁

I want to know what going to happen with that V12. Worked on aviation engine with twin spark. But this beast is more worrying

SUBBED your channel 👍seen u on Oak Swamp channel. Great vids and content on here! ARCO MN OUTLAW CUSTOMS (Outlaw edge KZbin channel )

great you TWINS got the crosley engine ticking over...yes the Lafrance fire truck engine..google Rod Hadfield v12 lafrance topolino hotrod in Australia...`Huge engine..would run on 6 cylinders to run the water pump hence 2 dizzys....good luck with that build

Watching the two of you working on that Crosley; you look like brothers from different mothers; especially when you both have the specs on! Love the content from both your channels; keep it up.

What a team. Like bacon & eggs. The Crosley is a sweet engine.Some mods to the intake and exhaust system should bring it up a few hp.

Excellent stuff. If only you’d already got a 12 cylinder engined car you could drop the La France lump into.

AWESOME.

Massive engine that American LeFrance, flat head? Destination not likely a single-seater, wouldn't want to straddle that beast. Thanks.

Love this dream team. Great to have two videos for the price of one. You two need to rescue a Barnfind. 👍👍

What a fabulous explanation, I’ve just fitted an SU HIF44 to our old Harley-Davidson Shovelhead , runs nice , it has a different feel to the previous carb . Thanks very much for a great video.

Not sure if you have seen the DEA upper case, but it is a beautiful crankcase conversion!

Hi thanks for the very informative tutorial.Question,if it’s the engine’s vacuum that raises the piston inside the carb,what happens when you’re cruising along say at 60 mph and you lift off the throttle pedal,to slow down.Would the high vacuum created suck the piston up when you didn’t need more fuel at that moment.Apologies if I’m being really stupid,but I remember the old vacuum wipers going crazy in that situation.

Help I have just bought myself an Austin 7 special and it won’t accelerate? The su carb that’s on it doesn’t have a rod attached to the cap that goes into the slide? Or a spring. Is this correct? Thank you,Andy.

Lovely explanation. Like the out takes at the end. When can we expect a blooper reel?

Thank you, great explanation. I've used an H2 SU for up to 65bhp on supercharged A7 engines, if you are planning an engine with more than 12psi boost and cam/valves that will get you peaking power over 6500revs then go for an H4/HS4.

In my circle of seasoned souls, we always called a carburetor with a sliding piston like the SU & Mikuni to be a variable venturi carburetor. Thanks Chris. Super simple easily understood explanation.

Excellent explanation

I just took apart the SUs on a Daimler 2.5 engine I have, this has been a most interesting video explanation of what I was guessing at! Really enjoying you and Brian’s adventures on Oak Swamp too

Greatly enjoyed on carbs, great bloopers.

Excellent tutorial! The SU system for throttle response is so much simpler than accelerator pumps. So, to know if you have the perfect size carb for the engine you could mount your camera looking in the throat and take it out on the track to see if there's full travel of the slide at fully loaded and sustained rpm/cfm.

The 'number being the number of 8ths' doesn't work for the pre-war HV SU series carbs, only the later carbs. An HV1 is a 1" diameter, a HV2 is 1-1/8 and so on. There is supposedly a HV0 which is 7/8ths but I have never seen one. Around the same era there were also the OM and UBA carbs each being a 1" throat, same as the HV1. They all take the same rebuild kit. My Riley is supposed to have OM carbs but I could only find UBAs (off early Morris). The difference seems to just be where the mounting screws for the dashpot are.

Great Explanation, I've never heard of an H5 or HS5, could these be H/HS4 or 6? I have a feeling the 1" plus 'x' 1/8ths measurement relates to the diameter of the hole (and hence butterfly disc) on the engine facing side? Really enjoy both your video's and Brian's Oak Swamp shenanigans ! Keep up the good work!👍😎

engine sounds great.

It appears that with the brilliant circularly adjustable float bowl system you could drive your beautiful Austin 7 special upside down indefinitely if adjusted properly, notwithstanding Miss Beatrice Shilling's ( I learned her name from kind commenter here last week) modification which allowed momentary inverted or negative G intermittently without stalling out. Nice. I believe that since the slide is indirectly moved by vacuum pressure that it maintains a good mixture even when driving at high altitudes. I live at about 3500 ft. elevation here in Mount Shasta, California, and frequently tour at much higher elevations such as 6700 ft or so and down to near sea level without needing mixture adjustments, just less power at elevation. I love my Skinner's Union carbs. Smarty pants.

Great explanation 👍

Great video! For my computing & electronics degree in early 90s, I designed and built a power-valve servo controller for my Ministock racing TZR 125, plus an LED rev counter. TZRs in the UK didn't have the controllers fitted and the valve was fixed in the closed position, you could also move it to the open position, but that then gave it no power at low revs.

I thought I understood these. I do now! Recently saw a Ford Pinto engine fitted with an SU carb. nice

No tickling?

Great explanation of a whole fuel system in the palm of your hand. Two cables and a pipe and your done. You got to love an SU.

Great explanation! Thanks 👍

Thanks for this really helpful I have to fit a morris minor carburettor to an Austin seven and was wondering about the fuel bowl height

Hi, Will you be in Pendine?

Happy days buddy, thanks for bringing us along

The mystery of SU numbers revealed! Great video Chris, good to see you and Bryan collaborating on a project (well sort of) - perhaps you need to give him a bit of encouragement to get his bit homework done!

Very glad to see you new apprentice Bryan wearing his Safety Crocs ! Great video.

nice bit of work as usual , how did you form the inlet bend or was it repurposed?. . I tend to use yorkshire fittings for all water pipe joints and manifold work. Good luck with the Hamble visit.

'ill get my coat'....hilarious

Who's are the L plates?

That SU information was pretty interesting. I didn’t know that about the sizing.

Can’t beat an ultrasonic cleaner.

2" SU's are popular here in Australia..though difficult to find someone who can work on them
