Due to starting problems, I replaced the camshaft on my Craftsman 18 hp lawn tractor model 917.272754. It starts every time now but will not throttle up and runs loud and somewhat rough (this was not true prior to this repair). The throttle lever visually appears to be working correctly. I did some research and wondered if I should have checked for TDC before aligning the timing marks on the cam and crank. I just dropped the cam in when the two marks lined up. I read about the possibility of being 180 degrees off on the marks since one gear is twice the size of the other if TDC wasn't verified. I am looking for information about this possibility before taking it apart again.
