It starts great but won't hold idle more than a couple of minutes before shutting down. It's been sitting for 8 to 9 months. I need advice. Thank you.

Does the ball pump up firm?
Filters?? 1/2 any?
Water in the system?
Could be the carbs need cleaning?
The needle/seat might be sticking?

The fuel: ethanol? over time the E breaks down the hoses and can clog the carb with gunk.

Check the gas for water?
Ethanol??
Ethanol draws moisture.
I bought a gallon of fuel last winter for the generator.
Went to test it for use. NOPE
Poured some in a glass jar, cloudy and full of moisture.

I have a '98 Force 90 that I'm working through idle issues on as well. The guys here are hugely helpful. If you haven't checked out the link and synch sticky, you should. I'm going through the procedure this week, praying I can static time it correctly and not muck everything up.
