Thanks but ive searched and can't find any :(

Really not that much TBH.

Turbo carb has additional sealing on the dashpot chamber, a slightly different dashpot screw/rod ( again for sealing purposes. And a vacuum leanout system to lean mixtures at part throttle.

Aside from that, they are essentially the same as a normal SU ( aside from needle and spring of course, but they arent necessarily turbo specific ).

IMO, if it was only a low boost setup, a normal SU would probably work fine. With maybe perhaps some thought given to sealing the dashpot screw/rod as it normally has a small hole in the top.

Thats most definately NOT a turbo carb.

Nope, not a turbo carb.

Turbo carbs usually have a clamp around the dashpot plastic screw top with a matching groove to secure it.
Dashpot screws are usually a domed nut type thing, not straight head screws as per normal carbs....Although any I had, I changed to Normal screws for ease of removal.

every one i've had i've had to hammer a socket/cut a slot into both the dashpot and flot bowl screws. i did see the proper tool for em on ebay a while ago but i got outbid.

both the ones ive got were socket head, with a little alloy plug to stop the likes of us tampering with them....strange eh

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

Mine have been hacksawed through to use with a flat head screw driver.

Back once again like a renegade master

i think those screws came in later to stop us lot twiddling with them

Little did they know that we're not idiots and pliers will undo them

My Mini build diary

Any I seen, way back when, had the security type screws on both float bowl, and dashpot.

But as I say, Any I had or worked on, I changed to normal screws. Im sure Im not the only person to do this over the years, and its been some years since Ive worked on one.

The Burlen rebuild kits come with normal screws to replace the anti-tamper ones. The only exception is the one holding the float shaft in.
