>> I am getting back to my Healey 3000 engine rebuild after two years. I bought the Roller master vernier timing gear set from Moss at that time. I have previously used the Roller Master gear set with multiple key ways to adjust the cam timing with
no problems on other rebuilds. What I don't like about this set is that the cap screws used to clamp the vernier gear to the hub are not very robust. Working in aviation I have AN-4 bolts that I can replace the cap screws with and safety wire them to prevent
slippage. Has anyone using this kit had problems? I could keep the cap screws and Loctite them. This is a street car, not a race car. Pictures are one bolt installed and the hardware side by side.<br>
