Yea I think that grabbing a brand new genuine Mikuni or Keihin from the states via evilbay works out cheaper than any rebuild of the originals.
On the pre-65 trials bikes people spend months begging for help with the old carbs, and the smart/tired ones just buy a modern jap carb to replace.
I’m 100% for keeping a bike original when it’s a classic, but I’d sooner replace moving parts with modern if I plan on actually using it. I appreciate keeping a bike looking classic, but it’s a similar argument to sticking modern rubber on it. Sod 1950’s tyres, I’d put modern compounds on and be glad it grips!
I decided against owning a classic, but when I did some research, a lot of the old Amal carbs are fickle at best.
You will probably find advice online (like I did) that you’ll be better served buying a Mikuni, or Keihin, with the correct in/out sizings. Keep the Amal, get it reconditioned, then leave it on the shelf and enjoy a perfectly running bike with a Japanese carb.
Even the Chinese knock-offs will run better. Worn slide will be making starting and idling hell.
