I wonder if some of you might be able to help me diagnose my problem. I just recently purchase a 17ft CC with a Johnson OMC 1991 115hp 2 stroke. Model number VJ115TLAIE. What I am experiencing is dificulty getting the motor started sometimes, and cutting out while idling, both in gear and out of gear. Here are the sysmptoms I see:
This unit has VRO. Once I start up there is no issue while running at speed.
When I come to rest and leave the motor in idle it will idle fine for awhile. 10-15 mins. Then I get an ocasianlay chuggin sound. The best way I can describe it is like the unit is huffing or sucking air. This will be followed by a stall if I do not increase my throttle up to around 1000rpm. Normal idle speed is about 700RPM
When i turn off the engine after being run for 30 mins or so. If i have it off for any period longer than 5 mins I have to choke it to get it started
I also am not able to just start it up in the netral position. I have to advance the throttle in netral to get it started, then let it run at 1500rpm for several mins before it will idle
When i do the start procedure above I notice that there is alot more oil smoke than normal, but once idling the smoke level seems normal.
I would think that after running at speed for 30 mins the engine should be warm enough to just start without choke, and without having to rev it for sevral min just to get it idling. Am I off base or do any of these symptoms point to things I can check/adjust to get this thing to start easier and maintain and idle?
