    I have a 91 Sambar ks3/4, carb. It was running rough on idle, and i want to replace the spark plugs and see if it gets better. It is labeled "JER3HS" made by Jorin. What is the equivalent spark plugs i could use?

    Thank you.

    The Jordan site doesn’t list the specs on the plugs, so you can’t work backwards to spec another manufacturers plug.

    Hopefully someone will post a plug from one of the other manufacturers.

    I ended up putting in NGK BKR5E, after referencing some older posts here. Truck runs smoother now.
