I'm trying to determine why I get no advance at higher RPMs on my '47 H. Back again with more information. The distributor is an HC5-757925 - from the flange that the clamps clamp onto (other numbers on the dist. housing are 353989R1 and 52 but I think that's for the housing part). Disassembled down to the cam. On the side of the cam that faces the dist. shaft plate there's a cylindrical post that fits into a hole in the dist plate. With the cam dropped down over the dist. shaft and this post in the hole, the cam can only rotate about three or four degrees. This appears to be the wiggle room of the post in the hole. I would expect the cam to be able to rotate 20 degrees, as it's being levered by the weights spinning out. Any ideas on what the problem might be? All the parts are free of rust so it looks like it should be in proper working order.
