Re: Past the power curve ?
I have seen the bottomed out acorn nut issue and changed mine out as well. I also suffered from high rpm fuel starvation. Drilled out the lower fuel petcock and put in a larger fuel filter. The guy at the lawn mower shop told me to always use the metal screen type filters for gravity feed applications. Paper type filters will not flow enough fuel. Problems solved and I now have plenty of fuel at WOT.
