i have a 79 camaro with a 750 cfm speed demon. the carb worked fine up until a little over a week ago. i haven't changed anything so idk why it isn't running good but it pops and barley runs when its warming up and i have to give it enough gas to have the secondary's open to run and even then its at like 15K rpm. and their is alot of exhaust smoke while its warming up to. am i getting to much gas or what? should i lower the floats? thanks
You should have instructions with the carburetor how to adjust the choke, and choke pull-off at start-up. If the choke valve and pull-off are adjusted too open or lean the car won't start without pumping extra accelerator pump shot into the intake manifold. If the choke valve is adjusted closed to tight the car will run rough and dump bluw smoke out the pipes.
