Old Style Touch Contol BlockRebuild

[joey j]

I am rebuilding an old style touch control block Casting number 351686R1 (The early Touch Control part numbers are 351981R1, and 354383R1 through 354383R4. Credit @Glen) on a 1948 Cub. The old style has some significant differences from the new style. I have searched this sight as best I could for a step by step repair complete with pics.like troop has done for the new style but cannot seem to find anything. Can anyone point me in the right direction? Otherwise I will document my rebuild and post it as I go.
Thanks,
Joey J.

I had to make one of the valve seat tools. I used some (7") of 1" x 3/16" bar stock I had in my bin and spent about 5 minutes on the "precision" grinding to make a 1/16" blade. I used a large adjustable wrench on the flat and had plenty of leverage.
