I was hoping it may slide off. The limiter cap has a slot in it, but not sure about the actual pilot screw. I haven't taken the time to try it yet with so much going on, but hopefully this weekend. My manual just says to turn the pilot screw out one turn I believe. I'll have to check again to make sure. But your manual seems to be the way I've always adjusted these small carbs. If I can't easily remove that limiter cap, I'll try removing the tabs.
Thanks,
Roger
