Need help with inherited 96 gti seadoo bombardier

[Polopro]

I got a seadoo from my father inlaw when he passed. It just made a clunk when I tried to start it. I have never worked on engines or owned a seadoo. So I took manifold off, took out starter, cleaned all connections, got water out of engin, put oil in sparkplug holes, ex. I finaly got it to fire up but it seems rough. Is there something I can use or put it the holes to clean it up. Out should I start it up turn flush hose On and let it run for awhile to burn off what ever is in there. Please help me my knowlege is limited to none. My bugget is supper tight so I would like to avoid costly repairs and taking it apart since I have I 2 year old that grabs everything. It's a 96 gti bombadier seadoo.

Try posting this in the 2 stroke forum for more help. It sounds to me like you have some bad plugs but I have limited experience with 2 strokes so don't take my advice too serious lol. The guys over on the 2 stroke forum will be able to help you out more
