    no answer can be given without saying what spec you aim to achieve, and even then its guesswork without a AFR.

    Hey mate... 180BHP isn't that easy... if you look at my car's specs on my profile you can see all the mods I did and I run 165BHP/220NM on the rolling road @ 20psi with my T2-T25 hybrid. I recently put in a gp A carb, just to test it AFR-wise... and it suited my car just fine without modifications. On my other std carb, I changed the a/c jet to 0.9mm and drilled the 2nd stage to 1.2mm. That's it!

    Southern carbs will supply jets if you need them.

    Why don't you buy some micro drill bits & do yours as necessary

    Well it sure feels like a lot more than 165... maybe that dyno wasn't very reliable

    oo im intrested

    if i want a 1.2mm 2nd stage, as said by jantheeven, what size would a standard jet be?
    i really want to find out what this carb is running as it fuels loads, and i belive has hesitation before boost due to this, mpg 16/18mpg on a good day, that cant be right for a "standard" carb or can they get that bad if say the mixture screw is wrong?
    what is the base mark like when on bike cabrs itll say something like" turn in to stop. 1 1/2 turns out"

    Re: Best jets

    2nd stage is non removable unless you fanct drilling it out and tapping an a/c jet in it's place but if you go wrong it's a new carb body you will need. The standard 2nd stage size is 1.0.

    Don't fettle without and afr gauge though matey.

    Easiest way to find out is taking it down to an MOT station and stick and emissons tester on it or buy and AFR gauge / setup i.e. LM-1 so you can see what it is doing through the gears and through the rev's.

    The a/c jet as you say sits just under the carb top it is just small flat head screw driver type and just simply unscrews.

    When you get your micro drill bits, you can try different sizes in your main jet and air corrector and see if they are standard. If you put a 1.2 drill bit into the main jet you would hope it would be pretty tight if it's loose then its been enlarged

    The standard size Jets for a solex 32 Dis should be

    1.25 A/c
    1.00 1st stage
    1.00 2nd stage
    1.20 Main Jet
    1.7 Needle Jet

    I am sure there is an article for all this matey might be worth looking in the article section when you come to play with jets
