I've got an ongoing bogging problem on my very new Honda GXH50 engine. I've tried all kinds of fixes (less-restrictive fuel filter, cleaning idle jet, etc.). But I think the problem might be staring me in the face. My engine's carb has a mixture screw that is designed in such a way that it can only move about 1/4 turn total. See the photo below.
I imagine that the unmodified GXH50 engine running in an application that it was designed for (water pump, cement mixer) might be alright with that narrow range of adjustment.
But on a motorized bicycle with a less-restrictive exhaust, a higher load placed on the engine, etc., it seems like that range is way too narrow to get the correct adjustment.
Has anybody here ever modified such a screw to open up the range of adjustment? I think I'll probably cut off the protruding bit that the red arrow's pointing at -- my Dremel should work nicely on that.
But I just thought I'd put this out there for your thoughts and advice.
Thanks for any assistance.
