Working on installing a TB143 kit in the 110. Im at the point of installing the gear on the cam. I have the lobes facing the down toward the piston and slid the gear on. One bolt hole lines up, but appears the other hole in the cam was drilled too far to the outside of the cam, (spacing between bolt holes in cam is too much). Anyone ever had this issue? I hate to drill the holes bigger in the gear because Id be affraid to effect cam timing. Ideas?
