ye are mistaking the needle jet with the pilot
106 is the needle jet
Depending on the age of the concentric the pilot is either a pressed in bush placed opposite the pilot adjusting screw or a screw in jet in the same place. Very old and 2 stroke concentrics have a screw in pilot at the bottom of the main body.The pilot adjustment is the horizontal screw.
Needle jets wear out in not too many miles and if rich running cannot be easily corrected needle and jet should be replaced

Depends just how "second hand" they are. Worn slides makes them useless until they've been reconn'd, then there's worn needle jets, chewed up/seized pilot jets, worn top cap threads etc etc.
Yep. Buy cheap buy twice. I was talking to the lads on the Amal stand at the Stafford Show this year and they quoted me £300 for a new carb for the A10 and a quick look on their website confirms this. I'd buy one at that price if i needed one.

« Last post by Craigy on 01.11. 2024 22:17 »Hi John,
I realised we were on different tracks 😁. No hassle.
One of the guys from club had a look for me yesterday and said the same about spacer size, I have replaced with a couple of washers which have given me enough clearance for the main chain behind the inner case. (I didn’t measure but reduced from approx 10mm to 5mm).
I’m just in the process of putting back together, all good so far. I’ve got the Cush drive and clutch basket etc back in place….just need to put plates back in, primary chain on, check front casing.
From what I can see, I haven’t altered the alignment of the shafts so all should be good there. Nothing is catching so far.
I’ll let you know how I go
