    Montego 640 bogs and sometimes takes off

    Looking for some help. just bought a 94 Montego. first run out on the water it wouldn't rev out then sometimes it would take off. I cleaned carb looked good. then while it was running I pulled the mag side plug wire and it shut off. then I pulled the pto plug wire off stayed running. I am getting spark to both. compression is also good. Temp sensor is not hooked up. I have looked at a bunch of old posts but most don't say what the problem was or could be thanks for any help

    First place to look on older Tigersharks is the fuel pickup tube. They are commonly cracked or broken off. Also try unscrewing plug boots and clipping plug wire back 1/4-1/2".

    Re: Montego 640 bogs and sometimes takes off

    Ok thanks for the suggestions. I will check the pick up tube. I did cut back the pto plug wire. I can start the ski with just the mag side plug wire on. but will not stay running or start with just the pto plug wire. Could it be the pto plug wire? And thanks again for any help.
