Ok, I've been here before with this problem, with no luck fixing it yet. 72 K20 Does not want to stay running right after a cold start. The choke closes fine but vaccume pulls it open as soon as it starts. The spring tstat is fairly new, I have tried to bend the choke linkage to adjust the travel but the vaccume piston is overriding everything. I kind of need to fix it because I use the truck for snowplowing. Thanks
