    Default 3 hp Trolling Motor may be Sears

    I purchased a antique 2 cycle trolling motor on e-bay and was told it is a Sears 3 hp (not sure this is correct). I have completly cleaned carb and fuel tank of all deposits. I can get it started (after lots of pulls) but am having trouble keeping it running (runs smooth when it does start). It has a Champion J17LM spark plug that seems to work best gaped at .30, is this the correct plug and gap? Also have the points gaped at .25, is this correct? If it was sold by Sears I am not sure if it is a Kingfisher, Tanaka, Craftsman, Ted Williams, Evinrude etc. Anything would be helpfull.

    Thanks,

    This is the closest I could find plugs champion CHJ8 I believe
    Called Champion and they do not make a CHJ8 spark plug (may be out of production). They recomended for a 3 hp 2 cycle a RJ14YC gaped at .35. I should not need the resistor so I will try a J14YC gaped at .35 (this is a little cooler pulg than the J17LM I am using).

    The only model info on it is "Model 51-B Serial No. 5629". Does this help?
