Have a 1973 Johnson 115v4. She had a intermitted starting problem.
Replaced Starter and Solonoid
Last year we had the carbs rebuilt.

When shes running.. She runs great, smooth all that.. Its starting
thats the main problem.

Starting- If the battery is fully maxed on charge it will start. but
it has to be a really fresh new battery or maybe a 2nd. But when we
try to start it on the lake with a less than 100% fresh battery (say
90%).. It wont start unless we wait awhile or we connect a jumper. I
have sprayed starter fliud at these moments when it wont fire and
nothing. . I can pull a plug andits either weak or no fire. Last
season we connected 2 batterys together. This worked for awhile.. it
would start every time for a time. Now thats not working. And
sometimes now not even jumping isstarting it.

I was told by a shop mechanic its most likely a weak stator. And this
has the symptoms of that because it requires high cranking RPM for the
plugs to show fire.

Also been told it could be the power pack.


So Far my plan is to replace the stator to start with. Any way I can
test the power pack? I have a multimeter and some other tools.

Thanks
