        I’m sure you can find the original screen, someone here should have one, or perhaps ebay…. I don’t think I would try to substitute or make up a screen…
        https://www.ebay.com/itm/OMC-9-9-or-15-hp-Drive-shaft-15-Johnson-Evinrude-321455-329510-341590/224078682567?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

        I only saw one on ebay, but it was more money that marineengine.com

        You could find a carb with an adjustable high speed needle, or perhaps just the bowl and the needle. But, you will have to modify the lower shrouds for this change.

        Or, you could order a fixed jet one or two thousandths larger. Please don’t attempt to drill the jet out. Have you had the jet out of the carb? Is it clean? Perhaps just soaking the fixed jet in engine tuner will solve the issue. These opening is pretty small on these little engines…It might look clean, but all it takes is just the slightest growth of crud from ethanol fuels to close it down a few thousandths and cause an issue. This growth is not visible to our eyes.
