Title: Twin 40s and cold idling Post by: Hawk on January 05, 2012, 01:41:45 PM Is there a trick to getting my Spider to idle when its cold. When warmed up, idle is perfect.
A couple of kicks of the loud pedal sees her start up every time but getting her to idle when cold is almost impossible. I'm contemplating adding a choke cable but wondered if there was a trick to it. Any ideas?

If you add a choke cable I'd be inclined to set it up more like a hand throttle so you can set a fast idle - in fact if your car is S1 or pre F/L you have provision for a hand throttle cable - don't know about F/L and later.

I'm used to motorbikes with flatslide carbs that don't like to be touched at all when cold - although I solved this on the race bike by setting the idle speed to 3k! I'll try giving the loud pedal anoccassional poke and see how I go. Mines a 1979 btw and I don't think there is a provision for a hand throttle cable?

I suspect the mount is still there on the throttle pedal. See if there's a mounting hole at the very top of the throttle pedal - you might be able to rig something up.

Title: Re: Twin 40s and cold idling Post by: WestonE on January 09, 2012, 03:01:36 PM Do not be tempted to connect the cold start devices on your Webers as this is not like a conventional choke it pours fuel in for a rich start and 2 pumps of throttle make them redundant. The danger of bore washing your oil away is too high with these bits connected. The hand throttle is a good idea although DCOE's are really race carbs and have never been great until warm tending to spit until the engine is warmed up.
