Dumbo The Flying Elephant

[Larry Hill]

I bought this nicely done engine part and it gave me some flexibility in tuning. I installed it but couldn't get it to repeat. Even the face runout would not repeat. I checked everything and everything checked good. Long story short, the dowel pin was protruding out far enough to make the hold down bolt washer apply in uneven force to the cam gear causing the runout to be everywhere.
A lot of times the parts are smarter than me.
