    1996 Johnson 15 hp no spark

    Just tried to crank my johnson 15 hp model number J15redg and would not turn over. I checked for spark and no spark. Replaced with new plugs and still no spark. Any suggestions? Should I replace the ignition coil assembly or the power pack first?

    Johnson 15 dies at idle

    Johnson model J15REDG dies while idling but at WOT runs perfectly. Does this sound like the carburetor is fouled up or can the idle be adjusted? The guy I bought it from said he rebuilt the carb but it has sat up in his garage. What do you think?

    1970 Johnson 9.5 model 9R-70C

When I put it into forward gear, it runs fine at low speed but when I get at higher speed the motor seems to bogg down considerably. When it does this I can stop and put it into neutral and rev it up...
