Three of the threaded holes for the air horn mounting screws were stripped by a previous owner. The screws are 10-24 RH so I ordered a Helicoil kit from McMaster-Carr, kit part number 91732A914. I wasn't sure at first whether it would be wise to change over to fine threads, but some online research told me that fine threads would be wrong for a soft metal like aluminum (too easy to strip) so I stuck with 10-24. Only other considerations were to remove the float and drain the gas out of the bowl (which I sucked out with a syringe) before drilling to avoid starting a fire and to mask off the carb body to avoid chips falling into the carb. Problem solved. I helicoil'd all four holes and I replaced the screws with allens because one of my originals was mismatched and I couldn't find the right style at the hardware store. . Finished...

When I bought my P19 two years ago it came with an offy twin carb manifold and an Edmonds aluminum head but not on thr motor. They head looks like it had been bolted down at some time because it has washer scars around the head bolts. It might have been sandblasted or something but the rest of it looks unused. The Edmonds head has helicoils in each hole. Did it come that way new? Could they have been added to reduce the diameter of the sparkplug hole? Who's got the cam to use with this set up? Who's got advise as to whether or not I should go this route or should I just split the manifold and go with the two B&B carburators? (Engine is already out as it had crankshaft issues not revealed by previous owner. Never's happened before, has it.)
