1972 Scamp in New Zealand
Ended up not going to training tonight so decided to get the cam installed and degree’d
found TDC, then set the Dti gauge up on the lifter (Ended up welding two old lifters together to make it easier to get the Dti gauge set up) found max lift and set Dti to zero, wound engine back .100” and then forward to .050” before max lift, noted the number the pointer was at on the degree wheel, the wound engine over until the lifter was at .050” after max lift again noted the number the pointer was on again,
added the two numbers together and then divided by two, this gave me 112.5° intake centreline. Cam spec card is for 102° so was a bit out. pulled it all apart and advanced the cam 4° and started again, ended up with an intake centreline of 101°,
so that where it will stay. Tomorrow night I’ll get the heads on an confirm there is no clearance issues.
