    1991 Waverunner LX 650 starting problems

    I recently bought a 1991 LX 650 in really good shape (all stock). It has a rebuilt carb and fresh plugs. On the trailer it will start instantly, but on the water it has a hard time starting. Could this possibly be a weak ignition? How do I change the sparkplug wires? How do I open the electrical box? What about coils?

    What I did on the lake was to lift the back half of the hull just off the water and it will start fine, but if it sits on the water it has a hard time starting.


    I'm thinking weak electrical. Any other possible ideas as to the cause and how to correct this?

    start problem

    First off will it ever start and run if it does ignore the rest of the post but if not check the compression, if the compression is low in one of the cylinders the ski will run fine on the trailer but when put under a load will choke out.

    Once it running it is fine. It runs its full rpm's with no problem. Is just a startng issue. I will have to do a compression check.
