92 Brumby with no choke
92 Brumby with no choke
Hi All,
As the title says my recently purchased 92 Brumby appears to have no choke. If memory serves (its been a while since I've had a brumby) the choke is set by depressing the accelerator pedal before you start the engine? Is this right or am I completely wrong? If what I am doing is ok is there anything obvious that I can check with the carbi/choke to see if I can get it working? Please take into account here that I am not the most mechanically minded person as well
Cheers,
Dave.

Your brumby will have an electric choke and yes you set it by (with the ignition to start) pressing the accelerator once before starting. Do you have the gregorys ? if not it is here
showthread.php?t=16439
section 8 is the fuel system
It could be a loose wire or the choke could need adjusting.
PS you know where I am

Not start position but the ignition on position.TOONGA wrote:Your brumby will have an electric choke and yes you set it by (with the ignition to start) pressing the accelerator once before starting.
I find tapping the accelerator twice, then start the engine works for me. If you touch the accelerator after the engine has started the choke will turn off. I've found that it is usually 2 things that prevents the choke operating correctly. 1) Power to the Choke Controller and/or 2) Choke Butterfly Spring

I have this on mine and it's lost the ignition feed to the electric choke... Someone had done a dodgy bypass to the positive side of the coil which was working. I have quickly neatened it up by getting power from the idle cut off fuel valve thingo on the carb which is also ign.
Some research I did.... It appears this power feed is controlled by a module under the dash which apparently gets a reading from a revolution sensor (more than likely the negative side of the coil). So when the motor is detected as running then the choke is supplied power.
My understanding is... Without power at the choke the choke would simply stay on and never turn off. The coil inside the choke heats up and this heat is what turns it off slowly over time. Like a mega old style timer. If I'm right then it's more likely the choke itself needs adjusting or is faulty not the wiring.
Like I said... This is just my understanding at this stage.

Yeah Dave, this is my understanding of it too. From memory, there's some sort of bi-metal thingie inside the choke controller that bends as it gets hot. I'm sure it stays powered whenever the ignition is on and only cools down when the ignition is off for a long period of time.SuBaRiNo wrote:I have this on mine and it's lost the ignition feed to the electric choke...

Me too and the best thing I like on the Subaru is that it used to tell me (light on the dash) when the engine was warm enough to push the choke back inCliff R wrote:Sorry, this is no help, but I do love my manual choke.

From memory there was a kit you could buy to convert from auto to manual but it's been a long time since I'm had to fit one.
