You must use a degree wheel to install the cam. The reason is because the chain and sprockets are off ever so little. It is not hard to do, but you should have someone show you how just to be certain its in as Howards said it should. They know more than anyone on how to get the most from their product.

the reason they do that is that some chains have some slack and having it advanced is probably better than retarted,i think the triangle is the advancing groove not the rectangle.there is always something to gain in degreeing a cam that way you know it's right.

usually the the cicle,dot and triangle are on the crank sprocket and in the directions that came with the kit they will tell you witch one means what and what markings are supposed to line up with each other. if you didnt get a paper with the timing kit i would call the company.
