AMAL Premier arrived...

... your post showing the Mk.2 info; the carb i have is the Concentric Premier

...Thanks you for your reply. 

i was just on the Burlen site, i entered their download site and found their "Color Runing Guide" which i downloaded. 

The other piece of literature i saw is the  "Hints and Tips" pamphlet which came in the AMAL box my Premier came in.  The "Hints and Tips" is a wealth of information, such the old b&w pamphlet that came with early Concentrics back in the day.  It seems clear to me that the "Hints and Tips" applies to the Mk.1 Concentric and not the Premier.

I also went into Burlen's "Technical" site which jogged my memory showing that removable pilot jet once the bowl is removed.  Burlen's technical article with it's explanations and many pictures is outstanding.  It's been a long while since I've been into a Concentric, so seeing Burlen's pic brought it all back

If there is another piece of literature that i am not seeing on the Burlen site, let me know; otherwise if the 2 pieces i mentioned above; we're good.  

As an aside, i have a pair of the earliest type Concentric that were once fitted to my Royal Enfield Mk.1A Interceptor.  These early Concentrics do not have the "button extension" on top of the tickler such as the Mk.1 Concentric has nor the removable pilot jet.  My '74 Commando has the Mk.1 Concentrics with the "button" atop the tickler; it's been 12 years since i was inside my Commando carbs, so i could not visualize the removable pilot...

The only thing i want to better understand with the Premier is how the adjustable pilot jet on the LH side works in conjunction the pilot adjusting screw on the RH side; this screw is directly in front of the tickler.  The old Concentric's were blocked off in the area where the adjustable pilot jet is now on the Premier.

... 50 weight Phillips 66 ashless dispersant aviation oil.  To add oil to the gearbox, as you have noted, the small filler opening does create somewhat of a challenge to add oil to the gearbox.  i have some 50 cc syringes, so I am thinking i will probably use one to put oil in the gearbox.  I note the drain plug at the bottom of the rear wall of the gearbox.  With oil already in the gearbox, how will I know how much more oil needs to be added without overfilling?  Or do I drain what oil is in the gearbox and add the factory specified amount?

Thanks for your comments on the use of bearing shields, shims and felts used to prevent oil from too rapidly exiting the gearbox.  Not really any different that the transmission on my '27 Harley.  I would imagine a certain amount of oil leakage is expected...?  I will look up the quantity the factory calls for to "fill" the gearbox. or is there an amount you fellows recommend to add...?

..."tun dishes?"  i think what you are saying about adding oil to the gear box is at some point oil will leak out faster from one area than the other, so experiment adding oil to a level that most slowly leaks...

...the plated cover that apparently is an interference fit? covering the kick start spring, should that slip off without to much fuss?  My cover seems to be held quite securely.  The reason i am asking, the return of the kick lever seems a bit weak and the p.o. sent along a couple new springs with the bike, so i am entertaining the thought of perhaps replacing the spring since the lever sometimes does not return...  not the easiest to grasp that cover, so before i were to attempt removing the cover, thought i'd ask!

Also, i am entertaining the idea of getting a kick lever that has the folding pedal...  Not yet sure i will replace the original, more of a thought than something i would actually do.  A while back, somewhere i read the type of folding lever that is used on later bikes can be fitted to the International shaft but i have been unable to find that thread.  Which model has the folding lever that can be fitted to the International? 

Kind regards
