    Golden Jubilee Evi Sportwin 10 - Should I convert?

    you will need to pull the cyl head and install a helicoil using the proper kit. use full metal inserts not the spring looking type. use some red lock-tite kit comes with a proper size drill tap and inserts did it on a 7.5 and all good.

    79’ Evinrude 70 Bogging

    It does seem OP had the carb work done in post #10 in theory eliminating that option & leading to a possible pump problem...... my thinking being that at higher RPMs the pump is getting a lot more pressure pulses from the crankcase to have it pull in more fuel for distribution to the carbs...
