    @pierodn do Andover have them in stock?

    I bought some last week, and none of my usual Norton haunts had them.
    Burlen Fuels (who make Amal) also doesn’t have them in stock.

    In the end, I ended up ordering them from Hitcocks (Royal Oilfield specialist) who sent them through the next day.

    ...seems there’s a world shortage of #19 pilot jets!!!

    it was reading this thread that caused me to order a pair from Andover, they were showing as in stock at the time of order but are now showing an un-availible.
    im hoping that they will help to solve my idle and overrun lean popping issue

    General question, but can't you open up the 17's with a 19 thou drill bit? (if one is available)

    Hate to say this, but some time ago I purchased 2 new Amals for an 850. Ran like crap, could not sync the left cylinder. Pulled them down and found machining swarf trapped in the jet body holder between main and needle jets. Returned them to vendor and wrote a wingeagram to Burlen who promptly apologied and sent 2 new ones. Ever since, (some 8 carbs on other jobs) I fully strip down and inspect and clean with solvent and air pressure, and check the float heights. After that, never had a problem and really like the new Amals.

    I only know that now with the old carbs overhaulled the bike runs great while with the new Premier was a nightmare.

    Maybe at this point, you cd send them back for evaluation. Perhaps they can examine them and tell you what's not correct?

    And I'd like to know a couple of things about the Premier:
    Is the idle circuit now actually more precise, compared to the old-style bush?
    Can you really remove the new pilot jets without pulling one of the carbs off a Commando?

    Not sure if they are more precise but you do have to remove one carb to unscrew the pilots. Also a lot of folks have said you can clean the jets out with a #78 drill, piano wire, stand of wire brush and many other ways. I made a holder for a drill bit and found it impossible to get it into the jet and gave up before I damaged them. It would be good if Burlen made a proper cleaning tool for the jets.

    Try attaching a spray can wand to the guitar wire or drill with crazy glue.
    Cheers,

    I've had some problems recently with new Premiers with the slide slightly sticking especially when the engine is fully warmed up. This causes the rpm to stay elevated for a while and then it may drop to normal or stay high. Idle is impossible to set as it fluctuates up and down. I know not to over tighten the flanges or you warp the carb and I didn't think I did. I use blue loctite and spring washers and just tighten until the washer is flat. But when I took the carb apart and tried dropping the slide into the top it would hang up. I used a pair of these(below) to sqeeze the carb body with the slide in the body. You may have to try several orientations to find the right spot but when you find it and release the pliers and the slide will drop on its own. Keep playing around with it until the slide will drop to the bottom of the body by itself. The anodized slides seem a very snug fit.

    That is certainly a damning review, htown.
    I cannot imagine taking a chance on having the slide stick open. What if it were to happen at WOT?

    As for having to squeeze one to make it round enough to work? Beyond the pale, IMO-

    Somebody asked about drilling out #17's to create #19's. This can absolutely be done. In ancient times, a mechanic's apprenticeship included drilling out jets, then soldering them closed and re-drilling them to another size. This was back before the prevalence of fuel injection.
