I need;

Bolt torque specs -

valve adjustment specs - loosen the rocker-nut just till it "ticks",

then turn till it stops "ticking" then another 3/4 turn. do it slow,

cause the motor will die if you do it too fast.

timing specs - around 10 degree BTDC (or go for max vac pull)

Thanks in advance


have fun..........

don't let the motor "idle" during the first 30 minutes. keep it
wound to between 1500-2000........... at different RPM's...

this will ensure you won't flat-spot the new cam...
