hello can anyone help me with these numbers that came next to dist. fo6i4j? on my 235 motor thanks and also the dist number is 1112396 4g27 D.R. and my question here is the vacum advance has a number of 076 on it and im having all types of problems trying to find a replacement for it. it is the type that has treads on the inside so you put the spring into and tighten it up on the hose fitting. the man at the parts store say when he looks up this dist. number it tells him that a vacum advance is not called for. can anyone tell me who might carry this type of V.A. and anything about this for my 235 thanks ted
