The Classic Marque

Thanks for all the comments, I had looked at Vizards chart and Daniel’s book too but perhaps I need to read the book specifically to understand Webers as I’m not quite sure what all these parts parts do , how they interact and what you would replace to change performance. As Dave says the car is a fast road sprint, hill climb car and I understood that smaller chokes can improve torque and driv...

Hi, any advice on removal of this non standard front shock on my YA. A standard armstrong lever arm has been converted to a modern shock but the weld has given way. Do I need to remove the inner wing / wing to get the lever arm off the studs or is there a better way to remove it fyi its the passanger side but I will also look at the drivers as not sure why it failed!

If you're going to dyno it I'd leave it alone and see what it does--It'd be a shame to stuff with it then find you need to go back to where it was. To me the mains are only just there but that depends a lot on the exhaust as well. If you're running a silencer then maybe they're pretty close but if it's a racer with a large/short exhaust the mains will need to be larger .
The dyno man will be ...

Wiring looks correct, I see you have a 'kill switch' fitted which makes a nifty immobiliser on this type of tach.

All you can do now is see how it goes with the coil connections correct. I'm sure you will then leave it alone, but me being me I'd reverse the coil connections again and see if it reoccurred :o) If so then running a reversed coil with this type of ignition is definitely to be...

He implied 200kW per radiator to me (rather than 2kW which a heater might be as you know). Still wrong though but they'd sure keep your shed warm 🤣🤣🤣

I watched the YouTube clip in complete disbelief. I began to think it must be some sort of AI skit.
Is he really as unfathomable stupid as that, and if not can he really be as shamelessly dishonest?
I'm insulted that he would expect anyone to swallow such unmitigated BS.

D McLean, you might want to revisit your arithmetic mate. 200W is a bit er- minimal for a bar heater!

I called Abingdon Spares today March 17, 2026 and they have 50 of these metal inner fascia supports in stock for sale. The day before, I went on their website and they did not have them. If you go on their website now, they may be listed as of today. If not, call them. Abingdon Spares part number 51-025A.

Mike, your setup looks pretty close to what Vizard recommends so I would go with it as is for a start.

If you want to understand more of how they work I would recommend a book by John Passini called Weber carburettors Tuning Tips and Techniques published by Brooklands books. I think it was pretty cheap when I bought it several years ago and it covers more than just the sidedraughts.

Thanks both.

Yeah, it was idling a bit lumpily, probably because it was cold and I hadn't pulled out enough choke- it normally idles somewhere around 700 rpm very comfortably once warmed up.

I think the RVC tach is wired correctly in my earlier (pre Aug 1972 chassis numbered car) -indeed, Paul, you were able to detect a slight tach dropping intermittently from my video indicating...

I was thinking 36s because it’s a sprint car rather than a racer.

Mike

I’ve found a pair of 36s. For some reason, I’ve also got 4x 34s and a pair of 40s! Surprisingly, no 38s 😀
