This is my old jet and the slightly used crappy AAT needle, and its not going back to my carb, Anyone wants my needle?? Just pay for the shipping.

oh , and handling fee as well.

Hahaha! Even sir Mal , can't believe that it can possibly happen... Ooops! Lol

EVERYBODY! That's an inside joke from a long time ago... all resolved now.
( Funny though, Malsal!)

That jet looks bent to me .......

The letters on the needle says AAC (??) there are no numbers tho.

1)my carb i believe is HS4.
2)998cc  A+ series engine 13k miles on the odo. ( if i ever want to sell this car, i will drive backwards so that the total mileage will decrease and will look new,,,anyway)
3) the timing is set i believe is at # 10
4) it set at 900sh rmp
5) valve clearance, im using the factory settings which is 0.012
6) spark plug gap is a 0.25  ( purist's gap) 
7) im using 5w-30 motor oil for dashpot
8) spring inside the carb is stock, still virgin, never been stretched.
9)i dropped the cylindrical thing inside the carb, no resistance/ok , i hear a good clank.
10)  throttle shaft movement about 60% ( i can tell , its a little worn out)
11) sir jeg, sir dan,  the TDM thing is too technical, how do i determine it, pls walk me through.
12) gas 87 unleaded
13) im using 3.0 amps flamethrower coil and  pertronix dizzy  6months in use.
14) newly installed high performace spark plug wires/ color red ( the    Wrapper says, "Congratulations on having purchased the finest quality ignition wire set available", ,  i felt good , reading it.
15) im using cone KN filter.  Attached to a 3 inch chrome pipping. Makes intake air cool.

Im having a hard time posting pictures, i post link to my photobucket and that link should be placed in between this ---> IMG right?but as soon as i do that, the p on the http got replaced by a smiley icon, is there a way to post pic correctly? How


and on the chart that you posted, mine is 99H, 1978-1983 and i needed to use ADE needle,, mine is AAC, so i got the wrong one.
i need to get the ADE needle

Oh my Gash! you won't believe this, i took off the current needle I'm using and discovered that the number is AAT ,i just bought this needle about 8months ago and started using it since then and a new jet as well, that was when the time i started experiencing on and off smooth and roughness on performance,,, the AAC needle that i mention previously was the needle i was using when i first bought the mini, and it was running perfect,no dieseling and starting is excellent that time,, now what i did was to install the AAC back, and oh gosh, the ride is super smooth,,yes i still have the gizmo pipe and KN filter on, ..i will observe till tomorrow and keep you updated.

Yes, but keep in mind that the mini it was tested on had a Maniflow freeflow exhaust manifold, the MiniSpares intake, an RC40 twin-box side exit exhaust. 

If he'd installed any of the K&N's tested on a mini with stock exhaust and factory needle, he'd have lost power.

In short, the mini had a PROPER STAGE 1 KIT and the venerable HS4 carb was fitted with the needle that came with the kit. 


In fact, I once tried to run my twin HS2 carbs without filters on the 850.  Of course, I was also using a small-bore LCB and twin-box RC40.  The result was that the mixture went wildly weak, rendering the vehicle almost undriveable.  So, slapped a pair of OEM paper filters (Coopers) into the air filter box and it immediately ran better; in fact I needed to turn the mixture nuts up one flat.  Sweet engine, that one was...

I think it was Calver who tested air flow through various filters and determined a slightly modified stock HS4 filter housing with i believe a K & N filter worked the best.

Yeah, i believe so too sir Mal, KN has the best non restrictive airflow among the rest,,, but then sir jeg has a good point too, Air intake should work hand in hand with the exhaust in order for the engine to run perfect, he stated that KN, doesn't do good if my exhaust is stock and has 1 inch bore pipe, and two mufflers, which i guess makes a lot of sense. i'm trying to analyze things and on how our mini engines and SU carb and filter and exhaust works...i think im getting a good grasp of it now...
