MECHANICAL QUESTION

  • March 22, 2011 5:55 AM PDT
    I recently bought a '72 Sportster (having had two Sporty's in the 70's I couldn't resist!) This bike was parked in a garage for 20 yrs and was told it was running well when parked. I re-wired her, new plugs and wires, points, condenser, new battery, cleaned her up, etc. She's a kick start and had good compression. Has an S&S Carb. When she finally started (after kicking about 3 lbs off my ass) she was running wide open, loud and strong, but I shut her down to avoid any damage. Is this a carb issue? Don't rag me too much, it's been a few years.....

    Either the carb, throttle, or cable is sticking.

    Thanks for your input. Atleast I'm still thinking in the right direction. Didn't appear to be the cable. Guess it's time to take the carb off and do some exploratory surgury.....

    It probably is gummed up from sitting so long.

    Yep, any bike that set for that long deserves a good carb cleaning...

    that would be the first place i would start I have a 69 ironhead that sat for 20 years too and i dident even mess with the old carb but got a new one

    which S&S carb? If it is the B, you might be better off getting a newer carb.

    I agree with the points above. Remove the carb and do a rehab. Clean and inspect thoroughly (carb and linkages). After sitting that long, it's a must do.

    Hey an S&S B with the atomizer is a kick ass carb as long as you're not running a full advance magneto! :-)
