Hi,
Now that the sub freezing temperature is finally here I was able to give my 70 Newport a true old start cold start. Two pumps of the gas pedal, hit the key, and it cranks to life quickly- however I noticed that for the first minute and a half of warm up, the exhaust is very rich (smoky) and the engine really burbles and is a bit shaky. The engine speed will pick up, smooth out and reach high idle after about 2 -2.5 minutes. At that point I can then tap the gas and the idle drops to a smooth healthy idle. My question is, can the choke be adjusted to not be set so rich? This carburetor was rebuilt over the summer and I never recall warmups having such a rich condition for the first minute and a half. Normally just fire up and go right to high idle. Any thoughts?
