FAQ Monday - Amal Concentric Carbs

We're often asked about our Amal Concentric Carbs, so in this FAQ Monday Ash is taking you through them and talking about pilot jets and which work better on which #nortoncommando [00:00] – Introduction and addressing confusion regarding modern Amal jetting notes found on the web. [00:25] – The change to the No. 19 pilot jet as standard for 850 Premier carburetors (and why it performs better than the old 17 jet). [02:02] – Visual side-by-side comparison of the Amal carburetor bodies showing why you can't easily fit a No. 19 pilot jet to an original old Mark 1 casting (pressed-in internal bush vs. external removable jet). [03:05] – Shifting focus to online tuning resources, specifically referencing the widely trusted "Bushman's Carb Tuning Notes." [03:43] – Addressing whether to use both the paper gasket and the black O-ring on a Norton Commando manifold installation (Pro tip: use the black O-ring only). [04:33] – Discussing problems with the float bowl drain plug washers—specifically how the hard red fiber washers can cause the drain plug to vibrate loose, and the shift to the new factory nylon washers. [06:08] – Final thoughts on the long-term reliability of Amal Premier carburetors and a strong warning about the dangers of leaving old fuel sitting over the winter months.
