Hi I,m new to the site but have been lurking and researching. Here is my question. So most re-builders say machining the top plate or shimming the armature is a band aid at best, hack job at worst and that the preferred method is to machine the poppet and seat. Now from what I can find new poppets and valve bodies are not available to us mere mortals, the re-builders may have a source but that is their lunch money we'd be messing with if they released their sources. No offence to the re-builders, everybody needs to put food on their table. Here is what I don't understand how is taking material away from the poppet and seat adds armature clearance. It seems to me it is almost like saying 2+2=4 but 1+3 does not equal 4. I'm not sure I get it, taking material from the poppet and seat should reduce armature clearance not increase it.
