Runner,
Great, sounds like you've got it.
Joe,
I thought that's what I've been saying, just not in those terms. Running a filter with the pin "out" is like running a bypass filter. It doesn't filter as much, but it does filter.
Again, I recommend pushing the pin in and running a Ford style spin-on bypass filter.
John,
all 54-58 261's are bypass only, just like the 235. Please make a note of it.
My 261 is from 1960 and it still has provisions for a bypass filter setup, like Runner was refering to in his manual.
