    OK i need ya'lls opinion. I have a rochester 4bbl carb with a standard choke, not manual not electric, its pissing me off, i start it the choke stays open till i hit the gas, and when i ran it today forf about 20 minutes it started to highrev and i had to take off the aircleaner and by hand hit the choke and then went back to normal.

    now heres the question, i am thinking about taking off the choke pull off and what not and installing a manual choke. do ya'll think this is a adequite solution or not?

    thanks for the opinion. cause damn this thing is pissing me off. it starts out fine, starts up and warm up RPM then hit the gas and it runs smooth at about 900 rpm idle then after about 20 min of driving the choke brings it back to about 1100 idle, now i dont have the electric i have the choke thats attatched to the manifold the lil box with the spring in side and the vacuum choke pull off. is it still the same conversion kit?

    im not too familiar with mechanical choke but all you should have to do it disconnect everything from the choke bracket on the carb and take a premade hose with cable running through it. Attach one end to the choke lever on the carb and a run it through the firewall and put a handle on the other end. Then place it where you want. Im gonna put mine by the trailer control near my right leg.

    Back in the 70's this used to be a standard mod on Rochesters and Holleys, especially after taking off the factory aircleaner and hot air riser tube.
