I’ve stripped, cleaned and rejected many Mikuni and KeiHin cabs over the years, but your Amal Monoblock looks so basic and well designed and very easy to work on! Caveat…using non-metric spanners of course! Thanks Simon, great video! 🏍️😎👍🇿🇦🍺
Yes Richard. The old Amal carbs are just so beautifully simple. I'm fortunate to have learned how carburettors work from working on such like - I don't think I would understand them if I'd started on some of the more complex modern models.
Hello, would like to have some tips on getting a slide out of a Amal monoblock (out of a RE Clipper 250, ~1958). Feels like the slide travels it's normal movement fairly freely, but then gets stuck with the needle clip just below the edge of the slide chamber. Wondering if the top of the slide chamber could be somehow deformed, and if so, how to get it back into shape again - or if there are any other ideas to check or try; Lubrication (several times..) seemed to help a little bit, but there seemed to be a limit to that. As it now is, I can't get the throttle or the slide cables disconnected, so can't get the carb to a bench or anywhere away from the bike to give it a proper cleanup.
Oh, and as of the markings on the carb you present here, which you read as 3/5/32... wouldn't the first / be a 7, just lacking it's "line on the top"..? So, a badly stampted/worn-out 7, making the marking exactly what it is expected to be?
Just a little heads up on that plastic filter. The use of 'E' (ethanol) fuels and especially when its 'E10' will cause plastic and rubber parts to deteriorate and distort and that one has suffered. This will cause the classic bike and car sector a lot of issues. We had the same issue on Scania trucks when people started to us Bio Diesel and the fuel attacked all the nylon parts in the system especially the fuel pickup filter in the tank which just shrank and stopped the trucks!. Scania (and the others) had to produce all the parts out of a resistant plastic.
Excellent video! Do you have any videos on jetting and altitude? I just bought a Greeves. It's idling a little high and the engine has run away on the maiden voyage. I know it came from about a 4000 foot difference.
Very helpful thank you. The newer plastic floats have FRONT clearly marked on them.

@@SongsFromTheSaddle I really enjoy these videos! 👍
How come you did`nt take the jet block out ?
No need to for ultrasonic to clean through passageways

Good video. To assist in adjusting the float fuel height level, there is an Amal shim kit to fit under the needle setting/banjo
Thanks for the info!
Thanks! I wondered how the 'tunnels" were routed.
Watch your video back, when the light catches the carb just right the stamped number is 375/32 !
Solid well designed carb and so simple.
its always a good idea to renew the needle jet ( buy from Burlens you get the genuine parts ) as they do wear

Fantastic video, thanks for the upload ❤
Thanks Rod
Who's Rod?
Suddenly my Amals are running too well. I need to take them apart and figure out why.
😂
