Hey, i just picked up a 1999 Polaris SLH700 that had only 12.9hrs on it. I took it out on the water this last weekend, ran great! When it gets hot, it is difficult to start, i have to choke it all the way to get it started even when its hot. I was thinking it was a gas issue, my machine not getting enough gas... but when i looked under the seat i noticed the airfilters/carbs were loose!!! Could a loose air filter on a carb cause too much airflow and mess up the ratio??? Havent been able to ride since bolting down... THANKS FOR YOUR INFO!
