Hey Guys,
I am new to the forum and could use a little direction on my 96 Johnson 25HP.
I just got this rig and it has not been run in close to two years.
I started with a new fuel tank and fuel and got it started while in the drive way. It ran OK, but not great.
I took it to the water to test it out. It runs fairly good at low speed up to mid throttle. When I try to give it more throttle it will begin surging and try to die out. Cut back on the throttle and will smooth out.
My best guess is the carburator needs cleaning, but I would like to hear back about other possibilities.

Thanks,
R
