Using choke at cold start

AussieBlue · Oct 28, 2024

Hi all.
I recently bought a 2012 FE570 with 30hrs and 1100km on it.
It just had a new fuel pump and everything works a treat

.
I didn't know it had a choke so I just hit the button after a prime and it starts fine and idles a little low until warm but no issues.
I found the choke yesterday and tried it but it didn't want to start??
Turn the choke off and it starts

Does this mean it doesn't require choke for the ambient temperature where I live or is there a problem??
Cheers Paul

It's not really a choke, like a hot start- it might work if it's REALLY cold, it just raises idle, but usually too much. When the knob is in, it's the idle adjust screw. Generally I just hit starter button quickly to prime fuel pump, then it starts next hit immediately, use throttle to hold high idle for a bit then all good. Remember these things were designed in Sweden- little bit different ambient to most of Oz!

Lol, I thought that might be the case. As you say, it starts fine, just idles a little low . Thanks for your reply
