Every step in this rebuild of the engine, surfaces another problem. I rebuilt the Tillotson carb with a kit. Now I find a pretty drastic leak at the gasket separating the upper and lower casting. I have heard that these are notorious for warping with the engine heat. I never really confirmed a good flat planar surface and the top casting is pretty severely warped. I am sure that the best solution is to machine the two to assure perfect flatness, but I am not sure where I could get this done. Is there any of the permatex products that might take up some of this warp and keep from leaking? I use the blue and black in many places, but I don't think either should be used in contact with fuel. Honestly I think the warp is so bad that nothing would resolve this. My other solution is to use a rebuilt Zenith I got two years ago that will not work due to such a bad sloppy throttle shaft fit. It came to me from a rebuilder I will not mention, and is the worst slop I have every seen in a throttle shaft. The car would start but would not stay at an idle, it was pulling in so much air. Maybe buying one of the oversize shafts or getting new insert bushings would help me to resolve this so I at least have a carb to get the engine started. Also when you get the bushings, is it clear what size reamer I would need to enlarge the holes for the bushings?
I am going to sell this car to the father of a friend and have promised him I would finish to get the engine running well, and he can take the car the rest of the way. I don't intend to do a "work around" that leaves him with a problem.
