Re: Johnson HD-25 running issues

[Buccaneer]

Garry, after re-reading the "HD & HS Carb Adjustments"
page you sent, it mentioned an alternate way,
closing the high speed needle all the way, and starting
the outboard with the low speed 3/4 turn open.
Warm it up, tune in the low speed, then go to full
advance and tune in the High speed. I’ve always done
it the "other way" on every other outboard, but
this alternate way worked great on this HD-25.
As I was retarding the magneto, I caught on to
a secondary problem. When retarding to about "Start"
(from the Fast position) it would start running erratic.
The mag lever was vibrating some on the gas tank.
I pushed down on the lever to stop it from rattling,
and it started running normal. Couldn’t see anything
arcing, so I tightened the tension screw tighter
on the mag plate. I had to tighten it so it was a little
stiffer than I’d like, but it took care of the erratic
running, and then idled down smooth as a Swiss watch!
I think I finally have at least one good running HD-25!
Thanks for the help!

Prepare to be boarded!
