1985 190E 4cyl gas hard starting when cold

Engine will start right away, run for a few seconds then stall. You have to repeat this process about 15 times until the engine warms up enough to stay running. You can't touch the gas pedal at all until warmed up or it stalls. Once warmed up it runs just fine. Not sure how to properly set the idle either. Have adjusted the throttle cable at the adjuster nut by the throttle body to speed up the idle a bit. Help. It's the inlaws car and they are to old to have sit out in the cold. (Winnipeg MB) Thanks
