Having some problems with my motor.1984 Johnson 50 hp (J50TLCRM) It ran good last year, but not "great", would die sometimes while idling. This spring, motor ran bad. Here is what has been done so far to help remedy it. New gas tank and hose,new clamps on all fittings, cleaned and put carb kit in, new plugs. Replaced starter solenoid (unrelated, but figured I'd mention it)
Still, has very rough idle, but runs great at high rpm's. Also, runs great on muffs, but not water.
Now, I am not a HUGE mechanic at all, more of a parts changer! What I'm unsure of is,
1. I've read where the idle screw is supposed to be backed out 1 1/2 turns. (I'm not sure where this is on the carb)
2. Is there a set way to adjust the throttle linkages? Or, what is proper way?
I'm attaching a pic of the carb.
Is the screw #30 supposed to not be turned in all the way? If so, problem may be solved as it is currently snug.
Also, I don't have any compression readings yet, hopefully will soon though!
Thanks for anyone's help on this!
