I have a 78 silver ann. vette 350 w/ a Q-jet m#17059222. The engine will start and idle as long as I keep the choke almost completely closed. The moment I let go of the choke the engine immediatley stalls. I have to hold the choke closed in order for it to start even if the engine is at running temp. The carb is brand new and worked just fine, engine ran...9 mo. ago when it was last started.
Anybody got any ideas...
