It allows you to get the cam timing correct when assembling. After that it
is no different to normal timing wheel

...assuming that the gears and chain and tensioner are up to snuff, exactly
what is the big benefit for vernier adjuster when there is a single cam
acting on the valves.. dp

>> 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.
