    idle rough on cold start

    I have a 1989 power ram 50 2.6l with a Weber 32/36 dfve carburetor within the last week when I start it idles rough but after it warms up idles fine I checked the high speed idle screw and it is in as far as it goes any ideas on what to check next would be greatly appreciated

    I had that sort of issue and the screw behind the choke might help, fast idle. What is the rpm's that it idles at? Should be around 1500 to 2000. Make sure your choke isn't closed off to tight or not enough also. It will load up on the plugs and cause it to miss. Mine does it sometimes when it's really cold outside. Check your plugs first and see what's happening. Burning rich or lean, make adjustment after.

    Have you adjusted the choke spring to ensure the choke works properly? If it is not adjusted right, it will not set and step properly, causing rough idle at startup. When properly set, 1 push of the pedal should close the choke plate, one tap after starting should drop it to the first notch on the cam, then it should step down as the spring warms up. The choke spring is thermally activated - the release of the choke is dependant on how tight the spring is against the choke plate. The screw that rides the choke cam sets the engine speed while the choke is operating. Hope this helps.
