cam timing

so my car is only going to 4000rpm and stays there. i know it has to be something with the cam timing for it to do that because thats all we have done. does it mean its way to far advanced and needs to be retarded alot?

Stock mechanical/static timing is 10* btdc.  Align the sprocket marks to the marks on the belt cover, disconnect the spout, start motor, check timing w/ light.

should the ignition timing crank notch be pointing at the cam timing at TDC?

did you align the mark on the timing chain with the one on the crank gear? im not sure if its a white mark on the cam gear or a dot on the gear, but there is a distinquishable mark on the cam gear that should line up with a mark on the crank gear

alright i have the white mark on the ignition timing crank pointing at the cam timing mark. so the cam pulley and ignition pulley are pointing at eachother and the crank pullet TDC mark is pointing to the bolt on the ignition timing pulley.

what brand of adjustable cam gear do you have?

most adjustable cam gears do not have a mark to line up with
