    denso vs champion plugs

    Have 1975, 70 HP Evinrude, manual calls for a L77J4 champion plug. Went to parts store to get new ones and they didn't have, they did a cross reference and it came up with a denso plug. Are these an OK plug or should I find somewhere to get Champion. I am told the gap is .040, is this correct?

    What needs to be done??

    I have a 1975 Evinrude 70 Hp 3 Cyl motor that on initial start and warm-up it runs great, put it in gear and stays running, the problem comes in a minute or 2 after I have been idling in gear. The engine will stall and then it is a bear to restart. After it does restart, I have to let it run...
