You mean the choke doesn't open all the way when the engine warms up? What year? My 80 did this (and buzzed a relay), until I replaced a fuse. Otherwise, it could be a simple adjustment. Do you have the shop manual?

Just had same trouble on my 73. Ends up the choke pulloff was bad. It is the solenoid with small rubber hose at front. I used vacuum pump or suck on it. it should pull choke off. Of course there is the thermostatic coil and adjustments. If you look for Lars carb papers there is a section on adjusting and testing divorced chokes
