Problem with Mighty Demon 750

OK, those look like the original restrictions...not drilled out and threaded for modified restrictions... that is what you need to start. Sorry, I could not see in there before. If you have a piece of 20 ga stripped solid wire it would juuuust barely not quite fit into a .031" diameter hole. A piece of 22 ga stripped solid wire would slip in easily. Or try a 1/32" drill bit.
