If you're hip-deep in Rochester fuel injection restoration, then you've needed some repair parts that were never offered as individual service replacements through GM. I'm talking about gear sets for high pressure pumps, fuel valves for sand-cast fuel meters, internal pistons for cold enrichment housings, steel sleeves for '57 - '59 spill valves, and exotic threaded fitting inserts. Then there are also the tiny cosmetic repair items like fast idle cam screws, point hold-down screws for '57 FI distributors, and male threaded fittings on spider feed tubes.
All of the above items have been available in dead-nuts correct form from only one source for the last 20 years: a shy machinist in Newark, Ohio named Rollin Jones.
Rollin is too sick right now to return to his home machine shop anytime soon. Actually, I doubt he'll ever make it back to work. He is even older than me, and has cancer with other serious health complications. I just wanted to tell the NCRS membership how much the injection world has benefited from Rollin's machining skills without most ever realizing it. I can't imagine how anyone can ever duplicate his work in the future.
The photo below shows some of his work. That fuel valve is made .001" oversize. The diameter can then be polished to create the proper .0005" clearance in the fuel meter bore.
