I have a 1938 "B" diamond engine in my 1931 SW . Can anyone tell me the difference in this engine compared to a model "A" engine ., diamond model "A " engine ,a 1932-1933 "B" engine. As usual all responses are appreciated .

I have an "A" dist and an "A" timing gear cover . If you time this engine using the proceedure for an "A" the timing ends up being advanced way to much. This advanced timing caused the engine to rattle , idle rough ,started acted up ,head gasket seeped and on occasion would vapor lock, no power in over drive . Now that I have retarted the timing it runs very smooth and maintains idle , starter does not stay engaged ,head seep disappeared ,no vapor lock ,no engine rattle, do not have to shift out of OD to get up small inclines . Not as peppy on take off but still keeps up with the rest of the cars in our model a club . Some folks on this forum have a B engine and an A dist and A timing gear cover and time it like an A and have no problems . This was not the case for me . Wonder why ?

Thanks Again .
