Being a machinist and having a big interest in F&J I've made a lot of parts for them over the years.  I can make just about any billet part you may need provided I either have one here to copy, have a measured drawing, or you send me your old part to copy.  Some of the many parts I can make are gears, studs, valves, governor shafts and bushings.  I can also rebuild or repair your worn or damaged parts like installing new valve guides, widening piston ring grooves or rebuilding ignitors.  Having castings made is not a problem provided I have a part of drawings to go by.  Due to demand I don't stock most castings, they are a special order item.  All castings and machine work are first class with strict attention paid to making an exact reproduction of the original part.  Parts leaving the shop are often better than they were new with tighter tolerances and better surface finishes.  I can and have done complete engine restorations too.  Contact me and I'll see what I can do to get your F&J back up and running again.
