How are you pressurising the float chamber ?

I did have the same problem and it was a broken needle. Since you tried different needles it shouldnt be your problem.

The turbo carb setup relies on the restrictor ring inside the standard plenum chamber to provide a pressure differential for the fuel chamber to pressurise. If you are running without that, then I think that is your issue.

Tonight I'll perform some tests. I'm going to Vintage Mini's, he has currently a running turbo engine mounted on a testbench. This makes it very easy to do testing with my carb:

do you hve a fuel pressure regulator connected to the boost source so it raises fuel pressure as the boost rises ? Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

I'd be interested in seeing more about this has been done. Sounds like a nice little project.

Hi Remko can we get in contact in Dutch. Im trying the same and got it only idling. But till last time it worked out. I made a mistake by the flowchamber. Small piston upside down. |

No rocketscience: 12 leds connected to 12 reed-contacts (or switch). Reed contacts in polyester block to fit to dashpot. Piston machined to hold a half 5mm whiteboard magnet. Simple, but very usefull while tuning the AFR! |
