| Subject: | Re: carb or fuel injection? turbo? |
Hi Noel,
No, it uses a diaphram that opens with airflow to supply fuel to the
metering tube with many small holes in it extending acroos the carb. throat.
A flat slide (the throttle) uncovers the tube, and thus more holes, as you
open the throttle. The mixture is adjusted by rotating the metering tube
so that the holes face into the airflow (full lean) or ~90 to the airflow
(full rich). There is also a separate simple mixture circuit for idle
adjustment. There is no float bowl, so it doesn't care which way up it is.
It will work with gravity or low pressure (2-6psi) fuel supply. They are
susceptible to hiccups with hot fuel vaporising on the ground due to having
no float bowl to separate the fuel from the vapour, but I have found it
clears immediately high power/fuel flow is demanded. Hot starts are
excellent cf. FI. I think they are a good thing, but there aren't a great
number of people using them so there is little corporate knowledge out there
about them. I like the lightness and simplicity, and will live with the
odd hiccup when hot.

We would appreciate input on timing a Lycoming 0-290-D that is using Bendix
mags. The info says to use 18 degrees, however I've heard someone say to use
25 instead-----Comments please.

Thanks I'll Google Elliston and have a closer look.
