Loren, I definitely have a 107A pump.  Are all 107A pumps the yellow dot pump or are some yellow dot and some

If the 107A doesn't tell me for sure, how can I tell which I have?

What will happen if I advance it to 1.15(?) and it's normal pump? (I don't want to break anything!)

It's acting like the fuel builds up and ignites when there's a pool in the cylinder, completely unrelated to
the injection time.
