My Street Demon install experience

You don’t necessarily need a choke. I live in a colder region. My car never had a manual or electric choke. All you have to do is pump the pedal 6 or 7 times if car hasn’t run in a couple days. It will fire right up. You just need to feather the throttle for 10-20 seconds until the engine builds a small amount of heat. When you restart the car after it being warm. It’s not needed there either. Just turn the key it will fire up with no throttle input needed. I actually removed my choke valve. So it doesn’t accidentally close while running the car. I put 5k mines on my engine never using a choke.
Do you need a choke, it depends....
I had the 625 street demon on my truck at 0 deg F start on the first crank, and jump up on high-speed idle.
Push the petal once, roll the engine and fire up to an idle speed, that I could walk back in the house until it warmed up. Way nicer jumping in a warm truck.
Did this several times, when my wife would steal my Jeep to get to work in deep snow.
