Hard starting when cold

[Mickey_D]

Actually, once mine is running it idles and runs fine without the choke. It will stumble a bit if I try to give it too much before it's warmed up, but normal "sane" driving it works just fine.

I have the same cold hard-starting issue with my Edelbrock-equipped '83, in addition to a very annoying stumble or hesitation right off idle.

Just a thought, but it may not be your choke at all. The Q-Jet carb is notorious for leaking fuel from the well plugs (there are 4 of them) of the main body. When (not if) this happens, the fuel bowl will go completely dry after a long sit. It then takes several turns of the crankshaft to pump enough fuel back into the carb's fuel bowl to start the engine.

If this is your problem, the carb will need to be torn down and the well plugs epoxied (JB Weld).

Sometimes I have an off-idle stumble, which feels more like a bog than a stumble, but that is only if I goose it a little to fast, which usually just spins my tires anyway.

I would really like to completely tear down the carb and rebuild it, resetting float levels, clearing jets, etc. But, since it is my only mode of transportation at the moment (my bike is taking a garage nap after a small mishap) it will have to wait until my bike is good to go and the weather is nice.
