Hello to all first off.

I have a 93 waverunner sx.

Got it from a friend for free, the engine was blown and out of the ski so I didn't get to see where things went. I put a new engine in it as it was running fine. Then all of a sudden a problem began and I have NO clue.
Starts and runs fine then all of a sudden it will start to sputter like it has a fouled plug. If you keep going at 1/4 throttle in a minute or two it will take off like nothing is wrong. Then 4 or 5 minutes later it does the same thing. There doesn't seem to be any real rhyme or reason. Some times it will start like that but after a little bit it is back to normal.

Any thoughts???
Thanks for looking
David

I assume you rebuilt the carbs and had a fresh tank of fuel, also premixed start up and break in oil?

Sure did. After doing some reading it sounds like it might be a temp thing. I'm going to look into that.
Thanks for the help
