Johnson 2 stroke problems

[Kramer]

My motor is a 40 HP Johnson Electromatic (2 stroke) RKL 27A (1965) I bought it last season and I think it may need to be looked at. Any input is appreciated. Problems are outlined below. I do own the service manual but I'm no mechanic and would not try to repair it myself. <br /><br />Problem one: Idles rough and stalls out. If I am in neutral it begins to shake and then stalls. Did this last season and this season. <br /><br />Problem two: I have had the boat out twice in the last week (first two times this season) . After trip one I was back home and I lowered the motor. When I did this I noticed a white substance and some gas dripped out at the bottom. A few days later while out fishing (with motor off) I noticed gas on the water behind the boat, at one point a series of big waves rocked the boat and I saw white spots in the water. They would float to the surface and then dissipate.<br /><br />Any thoughts are appreciated, I'll probably have to take it in before using it again.<br /><br />Giddyup<br /><br />Kramer

Get a manual.<br /><br />Probably needs a good tune up. Start with cleaning the carbs, plugs and more than likely you should pull the flywheel and claen all the contacts.<br /><br />AND Check your lower unit oil. See if it is milky or some may be leaking out. The gas on the water is probably due to a carb or ignition problem. Unburned fuel is making it to the water which would account for the rough running and stuttering.<br /><br />good luck.<br /><br />Bob

hello kramer<br />i am no expert at all but i am awaiting a post so i will do my best. white in my experience is bottom end oil mixed with water. it looks like milk. if a milky substance is leaking from the bottom end (lower unit) it has a leak in one of the many seals. its fairly easy to check and not too expensive normally to fix. gas is nowhere near the lower unit, i assume what you are seeing is oil.

Howdy, Kramer.<br /><br />I noticed that you have a manual but don't want to work on your engine.<br /><br />You have symptoms of float trouble in at least one carburetor. You also have symptoms of a leak in the gearcase. Both should be investigated and repaired.<br /><br />Good luck.
