Machining injectors

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.

Here's a rebuilder in Ms. that also sells parts. I haven't done business with them so cannot make any suggestions....

Re: Machining injectors

I think they are takng material off of the top of the injector, not the armature or sinking the poppet seat. That's why some heroes have claimed to increase clearance using a belt sander!!

I bought some small parts from Mylex years ago and they were good about it.

Re: Machining injectors

Thanks for the responses, I'll have to give them a call. I plan on rebuilding my injectors before next winter and I would rather replace worn parts as apposed to trimming in other area to make them work. I'm running the original injectors and the have a 252K on them. they are tired and I get a lot of smoke when cold but I'm getting over 16 mpg on a 350 cc with 35"s. Not sure how that is happening but I'm not complaining.
