New pair of carbs, or just replace the bad one.

I've finally decided to give up on one of my Amals, but have decided against switching brands. Not that I'm a purist, or have any opinions against other brands, but I just have a little more love than hate in our love/hate relationship.

I've been having issues with my left carb forever, and after having it off the bike for the 20th time, I noticed that it has some small cracking. Good news is that I finally have a smoking gun on my running issues, bad news is I need a new one.

Should I just buy the single carb, or is it best to buy them in pairs? Anyone got a left laying around that is salvagable? I already have new internals.

To me it would depend on how good the remaining one is. Age, sleeved or not sleeved. Then the question, "will the same thing happen to that one?". If you're confident the second one is excellent I'd probably just replace the one.

A lot of Amal Mk1s have what appear to be two hairline cracks-but they are marks left by the casting die.

It was cracked, and pulling air into the pilot circuit.

OK. Time for a new Amal Premier Mk1 (or two?)

Boy that is a nice picture of the new Amal carb. They will look that way for the first ride around the block at least. I should own stock in CRC Brakleen. I am running sleeved rebuilt stock carbs with stay-up floats and it is running pretty much like new or actually better with the Pazon Altair.

Still a believer...

Have to admit that when we voted for the best bikes at the Vermont Rally I looked at whether they still had the Amals.

i'll second that, it's also my go to bee killer!

My move would be to replace both carbs. I just don't think something used and worn and something new could ever be made to run together well enough. If there were a budget issue, maybe it could be tried, but differing slide clearances, how clean is the old idle circuit anyway?, etc. I ride mine so much I need it to behave!
