If you look closely at a Saito cam, the exhaust lobe is keyed into the notch of the intake lobe to keep it from rotating. The exhaust lobe is loose, and the only thing keeping it from rotating any more than it does it the that it is keyed in place. It seems to to have lost the press fit and become loose. Is this normal, or is it in fact defective and in need of replacement?
Now for my real problem: I cannot tell if I have a FA 120 L, or a FA 120 M. Horizon lists a cam for the models M-N, which are the FA 120 Special, and the FA 120 Special w/ pump and dual plugs. I cannot determine positively if mine is a special, I beleive it is an ordinary FA 120 , refered to as a model L.
I need help identifying if mine is a model L, or Model M. It appears model M has a threaded hole for the intake manifold, is that correct?
My FA 120 has a un threaded hole for the intake manifold, the manifold seals with an o-ring and just presses into the hole. The carb is held onto the back plate with a bracket which supports it, and the manifold.
I need to know if the M cam Horizon has will work in my FA 120 .
Thanks for any assistance in advance.....I long ago lost the parts list and box the engine came in!  Jay
