2005 Yamaha 150 2 Stroke Low Idle Issues

Hard to start and runs rough at low idle and dies. But ran good on high rpm's. I believe it might be a possibility that low idle jets could be gummed up. Took it in for service once before about a year ago and was told that it was the low idle jets. I thought I was keeping it cleared by running it at least once every two weeks. And using gas treatment in fuel. I have a 05 Polar 19 CC Dynasty.
Any advise what the problem may be and how to troubleshoot it? I would like to learn how to work on this myself.

If it comes back that removing carburetors and cleaning jets is a must what gasket set will I need? And what carburetor cleaner should I use in cleaning carbs once disassembled.
 
Report the results of a compression test !------------Check that you have spark on all cylinders that will jump a gap of 7/16" with a snap you can hear.-------------If those are good then look into fuel issues.
