Amal TT Parts - Information Section

Product no.: 0136 Info4
Listed here are reproduction parts to fit Amal TT carburettors. There were many variations of TT carburettors made over the years, with some subtle differences between pre-war and post-war versions. Norton carburettors were also slightly different to other makes. The majority of the parts shown here are generic and will fit all models.

10TT Mixing Chamber Cap Ring

Product no.: 0137 TT/3338
- Lovely quality chromed chamber cap to fit all 10TT Amal Carburetters -The type shown here is the type originally fitted to post-war TT carburettors, where the ring was secured using the retainer spring shown below (4/307) - Unfortunately the original pre-war type (which used a wider mixing chamber top and lockscrew) are no longer available. Therefore if you are replacing a pre-war type you will need to replace both the cap and chamber, as they are a matched pair. Note: RN Caps are a different diameter, so these will not fit. I am currently having a small batch of RN caps made - should be available Autumn 2009

10TT/RN Mixing Chamber Top

Product no.: 0138 TT/3334

Choke Tube to fit Amal TT Carburettors

Product no.: 0295 3438

If you are thinking of boring out your Amal TT to a new choke diameter - i.e taking a 1 1/16" bore out to 1 5/32", then you will first need to remove the Choke Tube. I can now supply this little but important item. I do not profess to be an expert on doing this - but I have done it a few times and I know the secret to removing an old one is to make a small tubular adaptor with a screw head, and a hole through it centre for a 2" x 1/4" bolt. You then put the bolt through the adaptor and the the old choke tube (which will be in situ in the old mixing chamber) and tighten it up. Put the mixing chamber in the oven until spit hot (to loosen off the old choke tube) then unscrew the adaptor and hopefully the old choke tube will budge. The small bolt ensures the screw head is kept tight against the choke tube. However, invariably this can get chewed, in which case having a new one is handy!
