Idles high with choke - normal?

[DimitriT]

My 550 will start fine in 20 degree weather with full choke but the RPMs will quickly rise to the 3-4k range. The RPMs then come down as I slowly back off the choke. Is this normal or do I have a leak somewhere. Everything else appears to work fine.

Very Normal.

I wish mine did that

It's not a choke , it's a fuel enrichment which actually delivers fuel to the
intake side of the butterfly. So yes the RPM will rise.

Enjoy it,that means its wanting to go for a ride.Mine will work just like a throttle after it warms up for a minute.I can set it anywhere from 1200 to 4000 rpm's
