    Engine locked up 97 gtx 787

    Started up my ski last night after putting a primer kit in. Was sure that nothing fell into the carb while doing it. It fired right up like nothing a ran great. Turned it off after 20 sec. went to start it one more time before going in and heard a clunk and then it locked up. Hand turned the crank backwards to fee it up. Cranked it over without the plugs and there is a weird buzzing noise. Put the plugs back and same thing. Sounds like itís bottom end. I was going to post a video on here but not sure if you can or not, can someone tell me if you can ? Thanks

    Sounds like something did fall in thru one of the carbs and rotary valve took on some damage. Why did you change over to a primer kit? Doesnt the 97 have accelerator pump?


    It is also possible the motor lockup has nothing to do with you adding that primer kit. If you are very lucky the wear ring in pump housing delaminated and that is the weird buzzing noise. If only you could be so lucky.....

    No accel pump on 97 GTX but yep sounds like something went down the carb.

    If you didnt remove carbs to install primer kit then you got what you got.

    Yeah I know. Still have 150psi on both cylinders so hopefully the damage it just on the rotary valve.
